THE THERMOCHEMISTRY OF ALKYLS OF TIN AND GERMANIUM.
Abstract
Measurements are reported of the heats of reaction of stannic chloride with tetramethyltin, tetraethyltin, tetrabutyltin and tetravinyltin in the liquid state at 25 C. The heats of these redistribution reactions are examined in terms of the bond-energy and bond-bond interaction scheme of Allen. Values are obtained for the heats of formation (as liquids) of Me3SnC1, Me2SnC12, MeSnC13, Et3SnC1 and EtSnC13. Accepting a measured value for the first CH3-Sn bond dissociation energy in Me2SnC12 (D1 = 56 kcal/ mole), the thermochemistry provides the second CH3-Sn dissociation energy (D2 = 32 kcal/mole), and another example of non-equivalent stepwise dissociation energies of metalcarbon bonds.
