Abstract
Cyano-bridged π-allylic palladium complexes of the type [Pd(CN)(all)]4(all = 2-methylallyl, 1,2,3-trimethylallyl, or 1,1,3,3-tetramethylallyl) are made by treating [PdCl(all)]2 with sodium cyanide (1 mol per g-atom Pd). These cyano-complexes react with tertiary phosphines or tertiary arsines (L) to give mononuclear complexes, [Pd(CN)all)L], having asymmetrically bonded allylic ligands, with 2 mol of sodium cyanide per g atom Pd, [PdCl(2-methylallyl)]2 gives [Pd(CN)2(2-methylallyl)]–. 1H N.m.r. and i.r. data are given and discussed.Keywords
