The synthesis of unsymmetrical diorganyl selanes was accomplished under electrochemical conditions in an undivided cell utilizing a magnesium cathode and a carbon anode made out of aryl and alkyl iodides and diselanes. This electrochemical cross-electrophile coupling (eXEC) was accomplished using a simple nickel catalyst formed in situ out of Ni(acac) and 2,2'-bipyridine in DMF at ambient temperatures. The reaction showed good functional group compatibility, and heteroaryl iodides, such as thiophene or pyridine derivatives, were well accepted.
在未分隔的电池中，以镁阴极和由芳基碘化物、烷基碘化物及二硒醚制成的碳阳极，在电化学条件下实现了不对称二有机硒醚的合成。这种电化学交叉亲电试剂偶联反应（eXEC）是在室温下于N,N-二甲基甲酰胺（DMF）中，使用由乙酰丙酮镍（Ni(acac)）和2,2'-联吡啶原位形成的简单镍催化剂完成的。该反应显示出良好的官能团兼容性，噻吩或吡啶衍生物等杂芳基碘化物也能很好地参与反应。
