Treatment of α,β-epoxy sulfoxides, easily prepared from carbonyl compounds with 1 equivalent of n-butyllithium at −100 °C gave the desulfinated epoxides in good yields. The similar α,β-epoxy sulfoxides having arylmethyl group at α-position, on treatment with excess n-butyllithium at −70 °C afforded 3-aryl allylic alcohols.
在-100°C下用1当量的正丁基锂轻松处理由羰基化合物制得的α,β-环氧亚砜,可得到高收率的脱硫环氧化物。在-70℃下用过量的正丁基锂处理时,在α位具有芳基甲基的相似的α,β-环氧亚砜得到3-芳基烯丙基醇。
