Palladium(II) and platinum(II) complexes of thiocarbamic esters

Abstract

The complexing behaviour of O-alkyl N-allyl- and O-alkyl N-phenyl-thiocarbamates towards Pd^II and Pt^II has been investigated. Palladium(II) form PdL′₂(L′= deprotonated phenylthiocarbamate), PdLCl₂ and PdL₂Cl₂(L = allylthiocarbamate), while platinum(II) forms only PtLCl₂; only in PdL₂Cl₂ is L monodentate, whereas in all other cases it is bidentate, bonding through its sulphur and ethylenic groups, or through sulphur and imide nitrogen. Triphenylphosphine form addition complexes with PdL′₂(probably four-co-ordinate) and PdLCl₂, while piperidine gives only four-co-ordinate substitution products.
