Pentacarbonyltungsten-coordinated selenobenzaldehydes, (CO)5W[SeC(C6H4R-p)H](R = QMe, H, CF3), react with ButS–CC–SBut by addition of the CC to the SeC bond to give 2H-selenete complexes; treatment of the selenete complex (RH) with NEt4Br affords the uncoordinated 2H-selenete and a 3,4-dihydro-1,2-diselenine.
五羰基钨配位的硒代苯甲醛,(CO)5W[SeC(C6H4R-p)H](R = QMe, H, CF3),通过在 SeC 键上添加 CC 与 ButS–CC–SBut 反应,得到 2H-硒络合物;用 NEt4Br 处理亚硒酸盐络合物 (RH) 得到不配位的 2H-亚硒酸盐和 3,4-二氢-1,2-二硒胺。
