Description
(R)-(+)-2,2'-Bis(di-p-tolylphosphino)-1,1'-binaphthyl is used as chiral catalyst ligand. (R)-T-BINAP complexes derived from rhodium precursors are used for the asymmetric hydroformylation of vinyl acetate. It is a catalysts used for reductive amination of ketones, Pt dications for cation trapping, Rh(I)-catalyst for hydrogenation of acetamidoacrylic acid derivatives.
