A Facile Method for Reduction of Alkene and Dehalogenation under Electrochemical Reduction Condition

A facile and efficient electrochemical strategy for reduction of various aryl alkenes/alkynes to aryl alkyl derivatives was achieved. The protocol was also suitable to dehalogenation of structural versatile aryl/alkyl halides. This strategy has good functional group compatibility to gain the desired products in good yields under mild reaction condition and air atmosphere with simple undivided electrolysis cell. The preliminary study of the reaction mechensm was carried out. Gram‐scale experiment exhibited the potential application of this method in practical synthesis.
