Sulfur-functionalized methyltin compounds nBu(3)SnCH(2)S(O)(i)R (i = 0, 1, 2; R = Me, Ph) underwent transmetallation with Grignard compounds MgR'X (R' = Me, nBu, Ph; X = Cl, Br, I) and diorganomagnesium compounds MgR'R" (R'/R" = Me/Me, nBu-sBu) to provide Sn(nBu)(3)R and Mg[CH2S(O)(i)R]X and Mg[CH2S(O)(i)R]R", respectively. Analogously, the reaction of nBu(3)SnCH(2)P(O)Ph-2 with Mg(nBu)Br afforded quantitatively Mg[CH2P(O)Ph-2]Br and Sn(nBu)(4). Transmetallations between it Bu3SnCH2YMe2 (Y = N, P) and MgMe2 proceeded only in the presence of catalytic amounts (10-20 mol%) of Lin Bu yielding Mg(CH2YMe2)Me and Sn(nBu)(3)Me/Sn(nBu)(4).
