摘要：

Contrary to earlier studies, mixtures of enetetramines A=A and B=B readily exchange their carbene units upon heating (100 - 175 degrees C) to give the cross-over olefins A=B. The absence of such exchange reactions has formerly been used as evidence against the dissociation of enetetramines into free carbenes by Lemal et al. and Winberg et al.
