Abstract
Abstract A series of Pd II complexes containing various Group V-donors were reduced with diisobutylaluminum hydride and the products screened as potential catalysts for the coupling of representative vinyl-and aryl-trifluoromethanesulfonate substrates to the Reformatsky reagent BrZnCH (CH 3)(COO t C 4 H 9. The desired coupling product was obtained only with “reduced” dichlorobis (1, 1-diphenylphosphino) ferrocene as catalyst ...
