ISOMERIZATION OF THE NITROETHYLENE RADICAL CATION

We recently reported on the generation of the hitherto uncharacterized nitrosoethylene (1) by low-pressure pyrolysis. The structural assignment was based on real-time collision activation mass spectrometric analysis in combination with isotopic labelling.2 The dominant fragmentation of the radical cation of 1 apeared as a simple cleavage of the C-N bond, the charge being localized on the C2H3 moiety in accordance with Stevensons r u l e . 3 ~~ The apparent absence of the oxazete structure ( 2 ) as neutral as well as radical cation was noted.

## 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
