This account deals with recent developments in organic synthesis with 1-haloalkyl
aryl sulfoxides, especially with 1-chloroalkyl aryl sulfoxides. 1-Chloroalkyl aryl
sulfoxides are quite easily prepared from alkyl aryl sulfides. Sulfinyl carbanions
and sulfinylated carbon radicals can easily be generated from 1-chloroalkyl aryl
sulfoxides. The sulfinyl carbanions were added to carbonyl compounds to give the
adducts, from which various kinds of new carbonyl compounds with carbon homologation
were synthesized. Optically active 1-chloroalkyl p-tolyl sulfoxides were obtained from optically active (-)-chloromethyl p-tolyl sulfoxide. Asymmetric syntheses of epoxides, α-amino aldehydes, aziridines,
α-hydroxy acids and their derivatives, and propargylic alcohols were realized starting
from the optically active (-)-1-chloroalkyl p-tolyl sulfoxides. 1.Introduction 2.Synthesis of 1-Haloalkyl Aryl Sulfoxides 3.Organic
