N-Phenylthioxocarbamates, obtained from the reaction of alcohols with phenyl isothiocyanate in the presence of NaH, were reduced with various silanes such as triethylsilane, triphenylsilane, and tris(trimethylsilyl)silane, as well as tributylstannane under radical conditions to give deoxygenated products of the corresponding alcohols in excellent yields. The reaction was applicable to not only simple aliphatic
在NaH存在下,将醇与异硫氰酸苯酯反应制得的N-苯基硫代氨基甲酸酯,在自由基条件下,用各种硅烷(如三乙基硅烷,三苯基硅烷和三(三甲基甲硅烷基)硅烷)和三丁基锡烷还原,得到苯甲酸酯的脱氧产物。相应的醇,收率很高。该反应不仅适用于简单的脂族醇,而且适用于糖和核苷。在相似条件下,还研究了使用氘代硅烷和氘代锡烷烷的区域选择性和立体选择性氘代。
