Sold in collaboration with Takasago for research purposes only.

Application

(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 α-imino esters.

Takasago Ligands and Complexes for Asymmetric Reactions

Catalyst involved in studies of the role of excess phosphine ligand in enantioselective conjugate addition of ethylmagnesium bromide and α,β-unsaturated ester

Reactant 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

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.
