The general strategy for the syntheses of trans-Pt(SAr)(CI) (PAr′3)2 (1) (Ar = Ph, C6H 4-2-Me, C6H4-3-OMe C6H 4-2-F, etc.; Ar′ = Ph, C6H4-4-OMe, C 6H4-4-Me, and C6H4-4-CF3) by the reaction of cis-PtCl2(PAr′3)2 with ArSH has been developed. The mechanistic investigation suggested that isomerization of cis-1 into trans-1 promoted by the combined use of C 6H6 as a solvent and pyridine as a base was the key to the successful preparation of 1.
