The reductive coupling cyclization of 1,I-dicyanoalkenes was performed with metallic samarium in saturated aqueous NH4CI-THF solution at room temperature. Sub-stoichiometric quantities of samarium could be employed and trans-isomer was the major product.

Allylic and propargyl bromides react smoothly with diorganyl diselenides in aqueous media to give allylic and propargyl selenides in moderate to good yields. The reaction need not be carried out in inert atmosphere. The speed is quicker than the same reactions in organic media.
