2-lithio-3-(tri-n-butylstannyl)propionitrile (1) with alkyl halides or carbonyl compounds gave the corresponding 2-substituted 3-(tri-n-butylstannyl)propionitriles (2), which were reduced to amines (4) and then diazotized to give alkyl cyclopropanes or cyclopropanemethanols, respectively, in moderate overall yields.
2-锂硫-3-(三正丁基甲锡烷基)丙腈 (1) 与卤代烷或羰基化合物反应得到相应的 2-取代 3-(三正丁基甲锡烷基) 丙腈 (2),将其还原为胺(4) 然后重氮化分别得到烷基环丙烷或环丙烷甲醇,总产率适中。
