Abstract

The ligands 2-(diphenylphosphino)aminothiazole (dppat) 2-(diphenylphosphino)amino-4-methylthiazole (Medppat) and 2-(diphenylphosphino)amino-4-tert-butylthiazole (Budppat) have been prepared. Reaction of these ligand with MCl2 (COD) gives [MCl(dppat-P,N)(dppat-P)][Cl], [MCl(Medppat-P,N)(Medppat-P)][Cl], and [PtCl2 ('Bu-dppat-P-2], respectively. The increased bulk at the 4-position limits the formation of a P, N system in Budppat. The X-ray structure of [PtCl(Medppat-P,N)(Medppat-P)][Cl] reveals that the monodentate ligand has undergone a tautomerism upon coordination. (c) 2004 Elsevier B.V. All rights reserved.
