Carboalkoxyethyltin compounds undergo redistribution reactions at faster rates than similar unsubstituted alkyltin compounds.In redistribution reactions between SnCl4 and carboalkoxyethyltin compounds stable intermolecular complexes are formed.Rate enhancement is explained in terms of intra- and intermolecular coordination effects.Where strong intermolecular coordination effects are observed, specific electrophilic cleavage of the carboalkoxyethyl group can occur in preference to alkyl cleavage in mixed carboalkoxyethylalkyltin compounds.The presence of a β-ester function can catalyse both alkyl/chlorine and alkyl/alkyl' exchange reactions.
