Synthesis and carbonylation of [Pd(Me)(OMe){(S,S)-bdpp}][(S,S)-bdpp =(2S,4S)-2,4-bis(diphenylphosphino)pentane]

Abstract

Synthesis of [Pd(Me)(OMe){(S,S)-bdpp}]2 by NaOMe metathesis with [Pd(Me)(Cl){(S,S)-bdpp}]1 is reported along with the low temperature carbonylation of 2; the elimination of methyl acetate from the new carbonylation product [Pd(Me)(CO₂Me){(S,S)-bdpp}]3 proceeds readily even at –50 °C.
