Nucleophile-induced ring enlargement of 1-(1-iodoalkyl)silacyclobutane and 1-(1,2-epoxyalkyl)silacyclobutane into silacyclopentane. Application to the synthesis of 1,4-diol, 4-alken-1-ol, and 1,4,5-triol

Two methods for ring enlargement of silacyclobutane into silacyclopentane have been described. (1) Treatment of 1-(1-iodoalkyl)silacyclobutane with t-BuOK or AgOAc provided 2-alkyl-1-silacyclopentanes which were easily converted into 1,4-diols by oxidativ
