✦ Synopsis


Two distinct radical cations have been observed by ESR in a-y-irradiated solid solution of hexafluoro-1,3-butadienc in freon. INDO calculations of ESR parameters showed that they were the cisoid CC& and tiansoid (Gh) forms of the planar hesafluoroburadicne radical cation. The unpaired electron occupies a s-type orbital of a2 symmetry in Cqv and bg szmmclry in CHID_

## Abstract The conversion of the cyclobutene cation radical to the 1,3‐butadiene cation radical has been studied using MINDO/3 and __ab initio__ SCF MO methods. Not only smooth electrocyclic but also stepwise, non‐electrocyclic routes were considered. Both calculational methods agree that the pref
