Out of an in‐depth study of a range of sulfinyl compounds in the transformation of alcohols into chloro alkanes emerged (2‐methoxyphenyl)methyl sulfoxide as optimal Lewis base catalyst. While this catalyst allowed the synthesis of benzylic chlorides in turn‐over numbers up to 50, aliphatic alcohols are non‐suitable substrates due to competing Pummerer rearrangement.

烷烃的过程中,出现了(2-
甲氧基苯基)甲基亚砜作为最佳的路易斯碱催化剂。尽管该催化剂可以合成多达50个转换量的苄基
氯,但由于竞争的Pummerer重排,脂肪族醇不适合作为底物。
