refluxing THF resulted in the oxidative addition of the inactive R3Sn–C bond to the tungsten atom to yield metal-metal bonded complexes CH2CH(3,5-Me2Pz)2W(CO)3SnR3. While reaction of R3SnCH2CH(mim)2 (R = n-Bu or Ph; mim = 1-methylimidazol-2-yl) with W(CO)6 in refluxing dioxane gave only the decarbonylation complexes R3SnCH2CH(mim)2W(CO)4, no analogous oxidative addition of the R3Sn–C bond was observed
