Objective: The metal complexes of 1-(Phenylamino)-4, 4, 6-trimethyl-3, 4-dihydropyrimidine-2-(1H)-thione: preparation, physical and spectroscopic studies and preliminary antibacterial properties. Methods: Complexes of bidentate ligand containing N, S-bridge [M(pmpt)2(H2O)n] (M(II) = Cu, Mn, Ni, Co; n = 2 and M(II) = Zn, Cd, Pd; n = 0) derived from the reaction of Hpmpt ligand with metals (M(II) = Cu, Mn, Ni, Co, Zn, Cd, Pd) and characterized by various physico-chemical techniques. From magnetic moment studies, square planar geometry is suggested for Zn(II), Cd(II), Pd(II) complexes, octahedral geometry is proposed for Co(II), Ni(II) and Mn(II) and distorted octahedral for Cu(II) complexes. Thermo gravimetric (TG) curves indicate the decomposition of complexes in four to five steps. The presence of coordinated water in metal complexes was confirmed by thermal, elemental analysis and IR data. Free ligand and its complexes were assayed in vitro for their antibacterial activity against gram positive and gram negative bacteria using chloramphenicol as a standard market-drug. Results: The reported complexes were synthesized through greener protocol that is grindstone method by mixing the ligand and metal salts in 2:1 molar ratio. Products were obtained in good yield with sharp melting point. Conclusion: Studies have indicated that such complexes can be prepared by environment friendly approach which requires less time, simple workup for isolation and purification with good yield. The [Ni(pmpt)2(H2O)2] complex showed excellent antibacterial activity while other reported metal complexes showed weak antibacterial activity.

The reactions of a series of 1,2,3,4-tetrahydropyridin-2-ones (1) with diazoacetates (2) in the presence of copper-bronze catalyst yielded exclusively 3-oxo-2-azabicyclo [4.1.0] heptanes (3 and 4) in excellent yields with high exo-selectivity. Tetrahydropyridin-2-ones (1) with N-alkyl substituents were found to be more reactive than N-aryl substitutents. Among the various copper catalysts studied, copper(II) triflate was found to be the best catalyst while rhodium chloride, ruthenium chloride did not catalyze the reaction. The application of ultrasonic radiation enhanced the reaction rate and allowed the reactions to be conducted at room temperature.

Chemical engineers ensure the efficiency and safety of chemical processes, adapt the chemical make-up of products to meet environmental or economic needs, and apply new technologies to improve existing processes. HPLC of Formula: CCuNS. Introducing a new discovery about 1111-67-7, Name is Cuprous thiocyanate

A PRIMARY (barrier) film forms on the copper anode at an underpotential relative to the secondary (porous) film and exhibits a pre-peak or shoulder at -0.19 V (vs.SHE), for a 0.1 mol dm-3 KSCN electrolyte.The anodic peak current for the primary film is linearly dependent upon the sweep rate, while potential steps into the primary film region produce monotonic current decays with j = kt-1, consistent with a place-exchange mechanism for the initial formation of the barrier film.Upon stirring, the size of the primary film peak decreases as hydrogen evolution competes with the film-formation process.A porous CuSCN film begins to form at potentials 50-100 mV more positive than the barrier film, producing a larger peak at 0.01 V (0.1 mol dm-3 KSCN), equivalent to a film of 15-20 monolayers, with thicker films formed in more concentrated thiocyanate solutions.The anodic peak current for the porous film and the potential change to reach the peak are both proportional to the square root of the sweep rate, which is consistent with a model for film growth controlled by the resistance across the underlying barrier film.Raman spectroscopy reveals at least two distict S-bonded CuSCN species, one of which is lost upon partial reduction of the film, and is due to the barrier film.The remaining species has the same Raman spectrum as crystalline CuSCN.

Chemical research careers are more diverse than they might first appear, as there are many different reasons to conduct research and many possible environments. Quality Control of Cuprous thiocyanate. Introducing a new discovery about 1111-67-7, Name is Cuprous thiocyanate, The appropriate choice of redox mediator can avoid electrode passivation and overpotential, which strongly inhibit the efficient activation of substrates in electrolysis.

The synthesis and crystal structure elucidation of two novel polymeric copper(II) complexes has led us to propose a mechanism for the formation of 2-picolinic acid (pic) from di-2-pyridyl ketone (dpk) and benzoic acid from acetophenone. During studies into the interaction of copper ions with the dpk-acetophenone system, two complexes Na2(NCS)2(H 2O)[Cu(pic)2] (1) and Na2(H2O) 2[Cu(pic)2(NCS)2] (2) which contain pic coordinated to copper were isolated. The occurrence of (1) and (2) has led us to consider the Baeyer-Villiger rearrangement as a possible mechanism for the formation of (1) and (2).

A protocol for the copper-catalyzed oxidative self-coupling of alpha-amino carbonyl compounds has been developed for the synthesis of tetrasubstituted 1,4-enediones (Z -isomers) in moderate to good yields through the cleavage of four sp 3 C-H bonds and the simultaneous formation of one C=C double bond in the alpha-amino carbonyl compound. The strategy has the advantages of using readily available starting materials and of high stereoselectivity.

Cation-templated self-assembly of 1,n-bis(4-methylpyridine)alkane cations (n = 3-7) with CuSCN was studied and a series of new polymeric thiocyanate frameworks were obtained: {(bmpp)[Cu2Br2(SCN)2]}n (1), {(bmpt)[Cu2(SCN)4]}n (2), {(bmppt)[Cu2(SCN)4]}n (3), {(bmph)[Cu4(SCN)6]}n (4), {(bmphp)[Cu2(SCN)4]}n (5), (n = 3, bmpp; n = 4, bmpt; n = 5, bmppt; n = 6, bmph; n = 7, bmphp). The structures consist of 1-2D frameworks with the dications trapped within host network cavities. Compounds 1, 2, 3 and 5 possess the infinite two-dimensional polypseudorotaxane anion networks. Compound 4 has a novel 1D chain structure which looks like lotus root. The results demonstrate that the side chain of methyl substituent plays an important role in the fabrication of polypseudorotaxane structures. Furthermore, solid UV-Vis spectra, photoluminescence and photocatalytic properties at ambient temperature were also investigated.

Modeling chemical reactions helps engineers virtually understand the chemistry, optimal size and design of the system, and how it interacts with other physics that may come into play. Reference of 1111-67-7. Introducing a new discovery about 1111-67-7, Name is Cuprous thiocyanate

The syntheses, spectroscopic characterization (IR, 1H and 31P NMR, ESI-MS) and conductivity studies of the mixed N,P-donor complexes of copper(I) thiocyanate: [Cu(NCS)(py)2-(PPh3)], (2), [Cu(NCS)(Mepy)(PPh3)]2, (3), [Cu(NCS)(phen)- (PPh3)], (4), [Cu(NCS)(bpy)(PPh3)], (5), [Cu(NCS)(bpy)-(PPh2py)], (6), [Cu(NCS)(py)(PPh2py)], (7), (py = pyridine; Mepy = 2-methylpyridine; phen = 1,10-phenanthroline, bpy = 2,2?-bipyridyl), together with single-crystal X-ray structural characterizations of 2, 3, 4 (new polymorph), 5 and 6 are reported, which provides an opportunity to study the effect of the introduction of a pair of nitrogen donors, both unidentate and chelate, on the bonding parameters of the Cu/NCS/P system. Cu-P and Cu-N2(ar) are found to be similar [2.1974(5) and 2.091(2), 2.070(1) A for py2 adduct 2, cf. 2.1748(9)-2.200(1) and 2.071(2)-2.106(4) A for the counterpart values for bidentate adducts 4-6]. However, Cu-N(CS) and Cu-N-C are 2.013(2) A and 157.4(2) for py2 adduct 2 and 1.946(2)-1.981(8) A and 166.7(2)-176.58(2) for bidentate counterparts 4-6. The change is attributed primarily to the closure in the N-Cu-N angle [99.58(8) for py2 2; 77.7(6)-80.5(3) for N?N-bidentate donors 4-6]. In consequence of the increased steric profile of the Mepy ligand, we find the stoichiometry diminished to 1:1:1, which resulted in the formation of [(Ph3P) MepyCu(NCSSCN)Cu(Mepy)(PPh3)] dimers. TDDFT/CPCM calculations were used to clarify the type of transitions involved in the UV/Vis absorption spectra, and the corresponding experimental photoemission data were acquired. The 31P CPMAS spectra of the copper derivatives exhibit distorted quartets that afford values for 1JCu,P. Furthermore, the quadrupole-induced distortion factors were calculated, and in the cases of 2, 4 and 5, the quadrupole coupling constants were obtained, on the basis of the X-ray structures.
