What is (R)-(+)-TolBINAP?

Chemical properties

White to cream powder

The Uses of (R)-(+)-TolBINAP

(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.

The Uses of (R)-(+)-TolBINAP

(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.
