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
