And the article was included in Journal of Organic Chemistry in 2015.Synthetic Route of C24H34O2 This article mentions the following:

Rhodium complexes derived from conformationally transformable α,ω-bisphosphite ligands combined with a suitable alkali metal BArF salt as a regulation agent (RA) provide high regio- and enantioselectivities in the asym. hydroformylation (AHF) of three heterocyclic olefins. The outcome of the AHF could be exquisitely regulated by choosing the appropriate RA with an increase in the ee, the reversal of the regioselectivity, or the complete suppression of one byproduct. In the experiment, the researchers used many compounds, for example, (S)-3,3′-Di-tert-butyl-5,5′,6,6′-tetramethylbiphenyl-2,2′-diol (cas: 205927-03-3Synthetic Route of C24H34O2).

And the article was included in Journal of Organic Chemistry in 2004.Synthetic Route of C24H34O2 This article mentions the following:

A series of mono- and bidentate phosphites was prepared with (S)-5,5′,6,6′-tetramethyl-3,3′-di-tert-butyl-1,1′-biphenyl-2,2′-dioxy [(S)-BIPHEN] as a chiral auxiliary and screened in the asym. hydroformylation of butenenitrile. These hydroformylation results were compared with those of two existing chiral ligands, Chiraphite and BINAPHOS, whose utility in asym. hydroformylation has been previously demonstrated. One bis(phosphite) with a 2,2′-biphenol bridge was found to be the best overall ligand for asym. hydroformylation of allyl cyanide with up to 80% ee and regioselectivities (branch-to-linear ratio, b/l) of 20 with turnover frequency of 625 [h^-1] at 35 °C. BINAPHOS gave enantioselectivities up to 77% ee when the reaction was conducted in either acetone or neat but with poor regioselectivity (b/l 2.8) and activities 7 times lower than that of (S,S)-Kelliphite [(S,S)-I]. The product of butenenitrile hydroformylation using (11aR,11’aR)-[[[1,1′-biphenyl]diyl]bis(oxy)]bis[dibenzo[d,f][1,3,2]dioxaphosphepin], i.e. (R,R)-I [(R,R)-Kelliphite] was subsequently transformed into (R)-4-amino-2-methyl-1-butanol, a useful chiral building block.

Designing and developing materials with specific properties are nowadays important tasks. These could be achieved by choosing the adequate conditions, from a myriad of possibilities, being aware that slight changes in the preparation method could have major impact on the final material. With the work presented here, we are showing that kinetically controlled surface nano-structuring (NPs formation and deposition over solid supports) in scCO₂ is a versatile way for preparing active materials. Size, composition, morphol. and organization/architecture of supported metal NPs can be controlled by playing with the type of metal, metal precursor, reaction media composition (stronger or weaker reducing media) and different supports employed. Moreover, direct correlation between phys. (size, morphol., organization) and chem. properties (composition, surface chem.) are demonstrated with the systems catalytic behavior, yield and selectivity, exemplified with N-alkylation reaction of amines with alcs.

π-Extended Ligands in Two-Coordinate Coinage Metal Complexes was written by Muniz, Collin N.;Schaab, Jonas;Razgoniaev, Anton;Djurovich, Peter I.;Thompson, Mark E.. And the article was included in Journal of the American Chemical Society in 2022.Quality Control of Copper(II) trifluoromethanesulfonate This article mentions the following:

Two-coordinate carbene-M^I-amide (cMa, M^I = Cu, Ag, Au) complexes have emerged as highly efficient luminescent materials for use in a variety of photonic applications due to their extremely fast radiative rates through thermally activated delayed fluorescence (TADF) from an interligand charge transfer (ICT) process. A series of cMa derivatives was prepared to examine the variables that affect the radiative rate, with the goal of understanding the parameters that control the radiative TADF process in these materials. Authors find that blue-emissive complexes with high photoluminescence efficiencies (Φ_PL > 0.95) and fast radiative rates (k_r = 4 x 10⁶ s^-1) can be achieved by selectively extending the π-system of the carbene and amide ligands. Of note is the role played by the increased separation between the hole and electron in the ICT excited state. Anal. of temperature-dependent luminescence data and theor. calculations indicate that the hole-electron separation exerts a primary effect on the energy gap between the lowest-energy singlet and triplet states (ΔE_ST) while keeping the radiative rate for the singlet state relatively unchanged. This interpretation provides guidelines for the design of new cMa derivatives with even faster radiative rates in addition to those with slower radiative rates and thus extended excited state lifetimes. In the experiment, the researchers used many compounds, for example, Copper(II) trifluoromethanesulfonate (cas: 34946-82-2Quality Control of Copper(II) trifluoromethanesulfonate).

The functionalization of C-H bonds in light alkanes, particularly to form C-N bonds, remains a challenge. The dehydrogenative coupling of amides with C1-C4 hydrocarbons to form N-alkyl amide products with tBuOOtBu as oxidant, and a copper complex of a phenanthroline-type ligand as catalyst was reported. The reactions occurred in good yields in benzene or supercritical carbon dioxide as solvents.

And the article was included in Journal of Organic Chemistry in 2022.Category: copper-catalyst This article mentions the following:

Described herein is a simple, novel, one-pot acylamination reaction of unactivated alcs.
