The reaction of a halogenated sulfone derivative of general formula (1):
wherein Ar is optionally substituted aryl and X is halogen, with a base can attain easy production of retinol useful in the fields of drugs, feed derivatives and food derivatives. The intermediate in this production can easily be obtained by reaction of a diol compound of general formula (2):
wherein Ar is as defined above, which can be derived from relatively inexpensive starting materials, with a Group IV transition metal halide without protecting the primary hydroxyl group.
