Synthesis, molecular structures and ESI-mass studies of copper(I) complexes with ligands incorporating N, S and P donor atoms

Equimolar reaction of copper(I) bromide with 2-thiouracil (tucH2) in acetonitrile-methanol formed a light yellow solid which on subsequent treatment with a mole of triphenyl phosphine (PPh3) in chloroform has yielded a sulfur-bridged dinuclear complex, [Cu2Br2(mu-S-tucH2)2(PPh3)2] 2CHCl3 1. A reaction of copper(I) bromide with two moles of 2,4-dithiouracil (dtucH2) in acetonitrile-methanol followed by addition of two moles of PPh3, designed to form [Cu(mu-S,S-dtuc)2(PPh3)4Cu] 2a, instead resulted in the formation of previously reported polymer, {CuBr(mu-S,S-dtucH2)(PPh3)}n 2. Reaction of copper(I) iodide with 2-thiouracil (tucH2) and PPh3 in 1:1:2 molar ratio (Cu:H2tuc:PPh3) as well as that of copper(I) thiocyanate with pyridine-2-thione (pySH) or pyrimidine-2-thione (pymSH) and PPh3 in similar ratio, yielded an iodo-bridged unsymmetrical dimer, [(PPh3)2(mu-I)2Cu(PPh3)] 3 and thiocyanate bridged symmetrical dimer, [(PPh3)2Cu(mu-N,S- SCN)2Cu(PPh3)2] 4, respectively. In both the latter reactions, thio-ligands which initially bind to Cu metal center, are de-ligated by PPh3 ligand.

The Cu(I) thiocyanate complexes with N-allylquinolinium: Synthesis and crystal structures of [C9H7NC3H 5]Cu(SCN)2 and [C9H7NC 3H5]Cu2(SCN)3

The crystals of [C9H7NC3H 5]Cu(SCN)2 (I) and [C9H7NC 3H5]Cu2(SCN)3 (II) were obtained in the reaction of N-allylquinolinium bromide with CuSCN and NH4SCN in a methanol solution. The crystals of I are triclinic: space group P1, Z = 2, a = 8.619(2), b = 8.755(2), c = 10.463(3) A, alpha = 77.18(3), beta = 69.95(3), gamma = 79.38(3), V = 718.1(3) A3. The crystals of II are opthorhombic: space group P212 121, Z = 4, a = 5.744(2), b = 16.799(4), c = 17.980(5), V = 1735.9(9) A3. The structure of compound I is built of infinite linear {Cu(SCN)2-}? anions and the N-allylquinolinium cations bonded additionally by relatively weak hydrogen contacts C-H…S. The [C9H7NC3H 5]+ cations are located between the corrugated layers of the {Cu2(SCN)3-}? anions in compound II. As in the case of the previously studied copper(I) halide complexes, the C=C bond of the allyl group in the N-allylquinolinium cation of complexes I, II does not interact with Cu(I).

Process for preparing aminobenzocyclobutenes

A process for preparing a 3- or 4-aminobenzocyclobutene comprises aminating a 3- or 4-halo- or sulfonyloxybenzocyclobutene reactant with an aminating agent by heating at a temperature from about 80 C. to a temperature at which dimerization or oligomerization of a benzocyclobutene reactant or product is a significant side reaction, in the presence of a metal-containing catalyst, for a time sufficient to aminate the halo- or sulfonyloxybenzocyclobutene reactant. In another aspect, this invention relates to a process for making a 3- or 4-phthalimido- or maleimidobenzocyclobutene, comprising reacting a 3- or 4-halobenzocyclobutene reactant with a phthalimide or maleimide compound in the presence of a metal-containing catalyst. The resulting phthalimido- or maleimidobenzocyclobutene can be hydrolyzed to a 3- or 4-aminobenzocyclobutene.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Reference of 1317-39-1, you can also check out more blogs aboutReference of 1317-39-1

2-Picolinic acid and benzoic acid from di-2-pyridyl ketone and acetophenone: A case of two copper catalysed Baeyer-Villiger rearrangements?

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).

These complexes are obtained by the reactions of CuX (X = Cl, Br, I, CN, SCN) with the bidentate ligand C16H6N6 and the monodentate ligand PPh3 in the molar ratio of 1:1:1 in the mixed solvent of CH2Cl2 and CH3CN(5 ml/5 ml). They are characterized by X-ray crystallography, luminescence, IR, 1H NMR and 31P NMR. In solid state the complexes 1-5 are mononuclear with similar structures, but in solution they have different structures according to their different 1H NMR signals.

Phosphate-free synthesis, optical absorption and photoelectric properties of Cu2ZnGeS4 and Cu2ZnGeSe4 uniform nanocrystals

Copper-based quaternary chalcogenide semiconductor Cu2ZnGeS 4 and Cu2ZnGeSe4 nanocrystals have been synthesized successfully via a simple and convenient one-pot phosphine-free solution approach. Oleylamine was used as both the solvent and reductant for Se or S and benefited the formation of homogeneous quaternary nanocrystals. Scanning transmission electron microscopy-EDS elemental mapping confirms the uniform spatial distribution of four elements in nanocrystals. UV-Vis absorption spectra of Cu2ZnGeS4 and Cu2ZnGeSe4 nanocrystals show strong photon absorption in the entire visible range. The photoresponsive behavior indicates the potential application of Cu 2ZnGeSe4 nanocrystals in solar energy conversion systems.

Syntheses, structures and vibrational spectroscopy of some unusual silver(I) (pseudo-) halide/unidentate nitrogen base polymers

The meagre (structurally defined) array of 1:2 silver(I) (pseudo-)halide:unidentate nitrogen base adducts is augmented by the single-crystal X-ray structural characterization of the 1:2 silver(I) thiocyanate:piperidine (‘pip’) adduct. It is of the one-dimensional ‘castellated polymer’ type previously recorded for the chloride: ?Ag(pip) 2(mu-SCN)Ag(pip)2? a single bridging atom (S) linking successive silver atoms. By contrast, in its copper(I) counterpart, also a one-dimensional polymer, the thiocyanate bridges as end-bound SN-ambidentate: ?CuSCNCuSCN? A study of the 1:1 silver(I) bromide:quinoline (‘quin’) adduct is recorded, as the 0.25 quin solvate, isomorphous with its previous reported ‘saddle polymer’ chloride counterpart. Recrystallization of 1:1 silver(I) iodide:tris(2,4,6-trimethoxyphenyl)phosphine (‘tmpp’) mixtures from py and quinoline (‘quin’)/acetonitrile solutions has yielded crystalline materials which have also been characterized by X-ray studies. In both cases the products are salts, the cation in each being the linearly coordinated silver(I) species [Ag(tmpp)2]+, while the anions are, respectively, the discrete [Ag5I7(py)2]2- species, based on the already known but unsolvated [Cu5I 7]2- discrete, and the [Ag5I7] (?|?)2- polymeric, arrays, and polymeric [Ag5I6(quin)](?|?)-. The detailed stereochemistry of the [Ag(tmpp)2]+ cation is a remarkably constant feature of all structures, as is its tendency to close-pack in sheets normal to their P-Ag-P axes. The far-IR spectra of the above species and of several related complexes have been recorded and assigned. The vibrational modes of the single stranded polymeric AgX chains in [XAg(pip) 2](?|?) (X = Cl, SCN) are discussed, and the assignments nu(AgX) = 155, 190 cm-1 (X = Cl) and 208 cm -1 (X = SCN) are made. The nu(AgX) and nu(AgN) modes in the cubane tetramers [XAg(pip)]4 (X = Br, I) are assigned and discussed in relation to the assignments for the polymeric AgX:pip (1:2) complexes, and those for the polymeric [XAg(quin)](?|?) (X = Cl, Br) compounds. The far-IR spectra of [Ag(tmpp)2]2[Ag 5I7(py)2] and its corresponding 2-methylpyridine complex show a single strong band at about 420 cm-1 which is assigned to the coordinated tmpp ligand in [Ag(tmpp)2] +, and a partially resolved triplet at about 90, 110 and 140 cm -1 which is assigned to the nu(AgI) modes of the [Ag 5I7L2]2- anion. An analysis of this pattern is given using a model which has been used previously to account for unexpectedly simple nu(CuI) spectra for oligomeric iodocuprate(I) species.
