摘要：

The indirect electroreduction of unsaturated alpha-bromoesters using Ni(II) complexes as electron-transfer mediators is achieved in N, N'-dimethylformamide by constant current electrolysis between a cathode and a sacrificial anode in a diaphragmless cell. Cyclic compounds are obtained in moderate to good yields in conditions that avoid the usual preparation using organotin reagents. (C) 2004 Elsevier Ltd. All rights reserved.
