Synthesis and resolution of a new P-chiral hydroxy phosphine

The synthesis of the functionalized P-chiral phosphine BzPhP{CH(OH)Ph}and its resolution by palladium metallacycles is reported. The cyclopalladated compound containing the primary amine 1-(1-naphthyl)ethylamine has been shown to be a better resolving agent for this phosphine than the corresponding metallacycle containing the tertiary amine N,N-dimethyl-1-(1-naphthyl)ethylamine
