Abstract
Abstract Oxidative addition of chloromethyl methyl sulfide to Pd(Ph 3 P) 4 provided a good yield of Pd(Ph 3 P) 2 (CH 2 SCH 3 )Cl (I) whose 1 H NMR and molecular weight data showed that dissociation of either the phosphine or the chloride ligand occurs in CH 2 Cl 2 solution. In accord with such equilibria, repeated crystallization of I from CH 2 Cl 2 and Et 2 O gradually removed the triphenylphosphine set free in these solvents to give the monomeric complex. Pd(Ph 3 P)(CH 2 SCH 3 )Cl (III), while treatment of 1 with NH 4 PF 6 in CH 2 Cl 2 and acetone gave the cationic complex [Pd(Ph 3 P) 2 (CH 2 SCH 3 ]PF 6 (II), 1 H NMR spectra of II and III are discussed in terms of a three-membered chelate structure arising from coordination of sulfur with palladium
