Stereochemistry of the thermal decomposition of (2-(acyloxy)alkyl)triorganostannanes

The stereochemical study of the thermal decomposition of (2-(acyloxy)alkyl)triorganostannanes revealed an anti β-elimination of (acyloxy)triorganostannanes. The process is highly stereospecific and not perturbed by the presence of a possible internal chelation favoring syn elimination. It corresponds to an open transition state. Kinetics of β-elimination in cyclohexyl and norbornyl systems showed that the reaction is much more rapid with a 180° dihedral angle between the metal and the ester group than with a 60° angle between the two. Stabilization of the partial positive charge developed during the transition state occurs mainly through hyperconjugation effect.
