REDISTRIBUTION REACTIONS OF β-CARBOALKOXYETHYLTIN COMPOUNDS

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.

β-SUBSTITUTED ALKYLTIN HALIDES. III. SYNTHESIS OF TRIALKYLTIN HALIDES AND TETRAALKYLTINS

(β-Carboalkoxyethyl)tin trihalides and bis(β-carboalkoxyethyl)tin dihalides react with metallic zinc to give mixtures of the corresponding tris(β-carboalkoxyethyl)tin halides and the tetra(β-carboalkoxyethyl)tins.Bis(β-carboalkoxyethyl)tin diacetates react with metallic zinc to give only the corresponding tetra(β-carboalkoxyethyl)tin compounds.The mechanisms of these reactions are discussed.Conversion of the bis(β-carboalkoxyethyl)tin dihalides into the tris(β-carboalkoxyethyl)tin halides is believed to occur by a two-step process, with the tetra(β-carboalkoxyethyl)tin compounds as intermediate products.The 270 MHz NMR spectra of the (β-carbobutoxyethyl)tin compounds are presented.
