Diethoxymethyltributyltin was obtained in high yield from the reaction of tributylstannylmagnesium chloride with diethylphenylorthoformate.It reacted readily with acetyl chloride to give chloroethoxymethyltributyltin, which was easily transformed to ethoxymethyltributyltin by reduction with tributyltin hydride.Diethoxymethyltributyltin, a masked aldehyde anionic equivalent, was metallated with butyllithium, and the resulting new organolithium reagent was trapped with benzyl bromide, benzaldehyde, and cyclohexenone.
QUELQUES ASPECTS DE LA REACTIVITE DE L'α-CHLORO α-ETHOXYMETHYLTRIBUTYLETAIN: ETHERIFICATION REDUCTRICE DES ALDEHYDES AROMATIQUES ET MISE EN EVIDENCE DE FORMYLTRIBUTYLETAIN LORS DE LA REACTION D'HYDROLYSE

α-Chloro-α-ethoxymethyltributyltin reacts with aromatic aldehydes and leads to benzyl ethyl ethers with formation of tributyltin chloride and carbon monoxide.Analogously the formation of ethoxymethyltributyltin and tributyltyn chloride on hydrolysis of this new organometallic reagent is explained by a process involving formyltributyltin as an unstable intermediate.This explanation is supported by the observation of an electronic spectrum between 350 and 450 nm during the hydrolysis.
