The information obtained from experimental and DFT studies has permitted the improvement of previously reported methods for the synthesis of both complexes in terms of reaction times, reaction yields, and atom economy. These studies show that complex 1reacts with a first equiv of SnMe4to form trans-[Pt(dmso)2ClMe] (2) as an intermediate that quickly reacts with a second equiv of SnMe4to yield cis-[Pt(dmso)2Me2] (3). When only 1 equiv of the organostannane reagent is added, the comproportionation of 3with the excess of unreacted 1leads the reaction back to the formation of trans-[Pt(dmso)2ClMe] (2). The mechanism of this comproportionation has been studied using DFT calculations.
