The formation of CF3SnBr3 and (CF3)2SnBr2 from the reaction of (CF3)2Hg and SnBr4 at temperatures of 112, 121, and 130°C has been followed in a semikinetic manner. The data indicate that the (trifluoromethyl)tin bromides are easily formed in reactions that proceed to equilibria, but the decomposition of more fully substituted species, e.g., (CF3)3SnBr, is almost immediate and severely limits the temperature range that can be utilized. The methylated compounds CF3Sn(CH3)3 and (CF3)2Sn(CH3)2 are easily formed in high yield. The latter reacts with excess Cd(CH3)2 to yield CF3Sn(CH3)3 while the former reacts with CH3Li to yield Sn(CH3)4. The formation of an unstable hydride, CF3SnH3, is also demonstrated.
