The Uses of TRIS(3,5-DIMETHYLPHENYL)PHOSPHINE

Catalyst for:

Cu / diphosphine-catalyzed asymmetric hydrogenation of heteroaromatic ketones and enones
Highly selective rhodium-catalyzed hydrogenation reactions
Classical versus kinetic resolution in preparation of privileged silicon-stereogenic silanaphthalenes

Used for kinetic resolution of donor-functionalized secondary alcohols via Cu-H-catalyzed stereoselective silylation by dehydrogenative Si-O coupling with Si-stereogenic silanes

Used for comparative studies of conformational rigidity of silicon-stereogenic silanes in asymmetric catalysis
