Description

Application

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
