Oxirenes to 1981 Summary

Another kind of elimination reaction which could in principle form oxirenes is -elimination. No systematic study of simple p-eUmination of halooxiranes seems 

A few attempts to test for the involvement of a benzooxirene are outlined in Figs. 3.9 and 3.10. Neither the phenol derivative 15 [56] nor the naphthols 16/17 [57] showed evidence of oxygen migration in reactions that may have generated carbenes (Fig. 3.9). Photodecomposition of the labeled diazo ketone 18 gave only ketene 19, indicating that a benzooxirene did not participate (Fig. 3.10). 

9 Elimination reactions on phenol derivatives give products which seem to arise from oxo carbenes, but the carbenes do not appear to equilibrate through oxirenes
