Sulfur Chelates 29. Ni(II), Pd(II), Pt(II), Co(III) and Cu(I,II) Complexes of O-Phenyldithiocarbonates

Abstract

Abstract The synthesis and characterization of metal aryl xanthates (O-aryldithiocarbonates) of Ni(II), Pd(II), Pt(II), Co(III), Tl(I), K(I) and Cu(I,II) are described. It has been shown that thallium(I) phenoxides, except with very acidic phenols such as p-bromophenol, add CS2 in hydrocarbon solvents. The thallium(l) aryl xanthates thus produced are useful reagents for the metathetical synthesis of other metal derivatives. With 2-alkyl substituents on the phenol, the potassium salts can be obtained which are used directly to synthesize other metal derivatives. The properties of the aryl xanthates are similar to those of other l,l-dithiolates. The complexes are somewhat more susceptible to thermal and atmospheric decomposition than the analogous alkyl derivatives.
