Diastereoisomeric cationic pi-allylpalladium-(P,C)-MAP and MOP complexes and their relationship to stereochemical memory effects in allylic alkylation

Abstract

The axially chiral ligands 2-(diphenylphosphanyl)-2'-methoxy-1,1'-binaphthalene (MOP; 6) and 2'-dimethylamino-2-(diphenylphosphanyl)-1,1'-binaphthalene (MAP; 7) coordinate to a cationic allylpalladium fragment in an unusual bidentate (P,C)-mode
