(S)-3,3′-Di-tert-butyl-5,5′,6,6′-tetramethylbiphenyl-2,2′-diol (cas: 205927-03-3) belongs to copper catalysts. Transition metal-catalyzed chemical transformation of organic electrophiles and organometallic reagents belong to the most important cross-coupling reaction in organic synthesis. Due to these characteristics, copper nanoparticles have generated a great deal of interest especially in the field of catalysis. Category: copper-catalyst

Synthesis of Molybdenum Imido Alkylidene Complexes That Contain 3,3′-Dialkyl-5,5′,6,6′-tetramethyl-1,1′-biphenyl-2,2′-diolates (Alkyl = t-Bu, Adamantyl). Catalysts for Enantioselective Olefin Metathesis Reactions was written by Alexander, John B.;Schrock, Richard R.;Davis, William M.;Hultzsch, Kai C.;Hoveyda, Amir H.;Houser, Jeffrey H.. And the article was included in Organometallics in 2000.Category: copper-catalyst This article mentions the following:

Two 3,3′-dialkyl-5,5′,6,6′-tetramethyl-1,1′-biphenyl-2,2′-diols (alkyl = t-Bu, 1-adamantyl) were prepared in two steps and resolved as the menthol phosphate derivative Addition of the dipotassium salt of each biphenolate to various Mo(N-Aryl)(CHR)(OTf)2(DME) complexes produced racemic and enantiopure compounds Mo(N-aryl)(CHR)(biphenolate). X-ray crystallog. studies of syn-Mo(N-2,6-i-Pr2C6H3)(CHCMe2Ph)[(S)-Biphen] and syn-Mo(N-2-CF3C6H4)(CHCMe3)[(S)-Biad](pyridine) proved the absolute stereochem. of the biphenolate ligands. Neophylidene and neopentylidene complexes have predominantly the syn conformation in solution The [syn]/[anti] equilibrium constant for Mo(N-Aryl)(CHR)[Biphen] complexes increased in magnitude with decreasing size of the arylimido ligand, and decreased upon reducing the steric bulk of the alkylidene substituent. The rates of exchange of syn and anti isomers, as determined by single-parameter line shape anal. and by spin saturation transfer, are on the order of ∼1 s-1 at 22°. 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: 205927-03-3Category: copper-catalyst).
