N2 - The reactions of [CpM(CO)3]2 (M = Mo, W) with PhSSnPh3, pymSSnPh3, Ph3SnH and pymSH have been investigated, leading to Mo/W-Sn bimetallic complexes. The mixed-metal compounds CpM(CO)3(SnPh3) (1, M = Mo; 2, M = W) are obtained as the only isolable products from the reactions of [CpM(CO)3]2 with PhSSnPh3, whereas similar reactions with pymSSnPh3 (pymS = pyrimidine-2-thiolate) lead to the formation of chelate compounds CpM(CO)2(2-pymS) (3, M = Mo; 4, M = W). Separate experiments show that CpM(CO)3(SnPh3) are precursors of CpM(CO)2(2-pymS). CpM(CO)3(SnPh3) can also be synthesized in slightly improved yield from the direct reaction between [CpM(CO)3]2 and Ph3SnH, while the yield of CpM(CO)2(2-pymS) becomes negligible when [CpM(CO)3]2 is treated with pymSH.
