Abstract

We describe the synthesis of a new asymmetric P, N, N′-tridentate ligand (bis (pyrid-2- ylethyl) menthylphosphine, BPEMP), containing two pyridyl rings and (1S, 2R, 5S)- menthylphosphino group. The ligand is obtained in five steps from natural abundant l- menthol. The coordination behavior of the ligand toward cationic (allylic) Pd (II) moiety and its first application in palladium-catalyzed asymmetric allylic alkylation are presented. ...
