摘要：
The reductive coupling cyclization of 1,1-dicyanoalkenes was performed with metallic samarium in saturated aqueous NH4Cl-THF solution at room temperature. Sub-stoichiometric quantities of samarium could be employed and trans-isomer was the major product. (C) 1998 Elsevier Science Ltd. All rights reserved.
