Description

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.

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.

Baeyer-Villiger Oxidation Reaction

The Baeyer-Villiger oxidation is the oxidative cleavage of a carbon-carbon bond adjacent to a carbonyl, which converts the ketones to esters and the cyclic ketones to lactones.
