摘要

Abstract This paper describes the synthesis of a new class of [N, P] ligands based on pyrrole with a dimethylamino group as hard donor and a phosphine moiety as soft base. We have also modified the phosphine fragment to change the electronic and steric properties of these ligands. Palladium complex 3a proved to be very efficient in Heck cross-coupling reactions and in intramolecular aryl–aryl couplings of esters and amides. We have demonstrated ...
