ジ-tert-ブチルクロロシラン

使用Considerable study of alkoxysilanes as intramolecular hydrogen transfer agents has been undertaken.The di-t-butyloxysilanes, prepared from di-tbutylchlorosilane and the requisite alcohol, are particularly effective and are generally stable to column chromatography.Treatment of a γ-iodoallylic alcohol with NaH and t-Bu2SiHCl afforded the corresponding di-t-butyloxysilanes which were exposed to UV irradiation in the presence of 10% hexabutylditin in the so-called unimolecular chain transfer (UMCT) reaction of silicon hydrides to afford the reduced alkene (eq 1）.
