Abstract

P-Chirogenic phosphine/sulfide hybrid ligands 1 were prepared by the use of optically active phosphine-boranes as the intermediates. The palladium complexes of the ligands exhibited high catalytic activity and enantioselectivity in allylic alkylation of 1-acetoxy-1,3-diphenylprop-2-ene with malonate esters.

Key words

asymmetric catalysis - allylation - palladium - phosphorus - sulfur
