Abstract
Reaction of trans-[PdCl2(NH2X)2](X = NPhR or PhCH2; R = Ph, Me, or H) with acetophenone gives the cyclo-palladated dimer [{PdCl(C6H4CMeNX)}2], the acetophenone phenyl ring being orthometallated. Reaction of [PtCl4]2– and [Pd2Cl6]2– with 2-aminothiazoline and 2-aminothiazole (L) affords in acid media the cyclic N-co-ordinated monosubstituted [NBu4][PdCl3L] and disubstituted cis-[PtCl2L2] and trans-[PdCl2L2] complexes. In basic solution, the monomeric [PdCl2L′2] and dimeric [{MCl2L′}2] species are obtained [M = PtII or PdII; L′= HS·CH2·CH2·NH·CN and HS·CH:CH·NHN. The combined presence of the metal and hydroxide ions appears to induce the ring opening and rearrangement of the amine ligands.Keywords
