Chiral diphosphinoditerpenes and their transition metals complexes

摘要

Chiral diphosphinoterpene compounds (I) are new. Chiral diphosphinoterpene compounds of formula (I) are new. *2, *3 : stereogenically marked carbon in R- or S- configuration where the substitutents are arranged in cis form related to the connecting carbon compound; and either R 1>-R 4>alkyl, arylalkyl, aryl or 4-16C heterocyclic group; or R 1>+R 2> and/or R 3>+R 4>alkylene. Independent claims are also included for: (1) compounds comprising (I) and borane; (2) preparation of (I); (3) phosphinyl compounds of formulae (IVa, IVb, Va, Vb, VIa, VIb, VIIa, VIIb, IXa and IXb); (4) transition metal complex comprising (I); (5) catalysts comprising the transition metal complexes; and (6) preparing stereoisomer enriched compounds in the presence of the catalysts.
