标 题 :Nucleophilic fluoroalkylation of aldehydes
发明人：STAHLY G PATRICK
权利人:ETHYL CORP
摘要:Aryl difluoromethyl sulfone adds to aldehydes under phase transfer conditions to give novel substituted alcohols of the general formula n n RCH(OH)CF.sub.2 SO.sub.2 Ar (I) n n wherein R is an aryl, cycloaliphatic, sec- or tert-aliphatic, or heterocyclic group and Ar is an aryl group. The substituted alcohols of formula I are of particular utility as intermediates in the synthesis of a variety of useful end products. For example, the products of formula I may be utilized in desulfonylation reactions, oxidation reactions and fluorination reactions.
