abstract |
Cyclic voltammetry and constant-current electrolysis in a one-compartment cell with a sacrificial anode has been used to study the indirect electroreduction of N-allyl-alpha-haloamides by electrogenerated Ni(1) complexes conducted in N,N-dimethylformantide (DMF) and acetonitrile (ACN) and the results were compared with those obtained in protic solvents such as EtOH and EtOH-H(2)O mixtures. It was observed that the indirect electrochemical reduction of N-allyl-alpha-haloamides led to the corresponding lactams and the yields and selectivities obtained in EtOH and EtOH-H(2)O were much better than those obtained in DMF or ACN.
