Electrochemical‐Induced Hydroxysulfonylation of α‐CF3 Alkenes to Access Tertiary β‐Hydroxysulfones

Abstract An electrochemical hydroxysulfonylation of α‐CF 3 alkenes was accomplished in this work. By using easily available sodium sulfinates as the sulfonylating agents, a series of valuable α‐trifluoromethyl tertiary alcohols were synthesized under mild and environmentally friendly electrolysis conditions in moderate to good yields. The preliminary mechanistic investigation indicates that this difunctional reaction involves a radical process via a sulfonyl radical. Gram‐scale synthesis shows the significant potential application of this protocol. magnified image
