Application

Catalyst involved in studies of the role of excess phosphine ligand in enantioselective conjugate addition of ethylmagnesium bromide and a,ß-unsaturated esterReactant serving as a precursor for: • Catalysts used for reductive amination of ketones• Rh(I)-catalyst for hydrogenation of acetamidoacrylic acid derivatives• Chiral platinum catalysts for asymmetric Baeyer-Villiger oxidation of cyclic ketones• CuI-Tol-BINAP catalysts for enantioselective Michael reactions of Grignard reagents to unsaturated esters• BINAP Pt Dications for cation trapping

Takasago Ligands and Complexes for Asymmetric Reactions

(R)-T-BINAP complexes derived from rhodium precursors are used for the asymmetric hydroformylation of vinyl acetate. It may be employed as chiral catalyst for allylation of N-tosyl a-imino esters.

General description

BINAP is based on a bis naphthalene backbone with different phosphine derivatives. 2,2'-bis(di-p-tolylphosphino)-1,1'-binaphthyl (p-Tol-BINAP)·AgF complex catalyzed asymmetric Mukaiyama-type aldol reaction is reported.
