9. In addition, several 3,5-disubstituted N-arylnitrones were used for the study, but they all gave rather unstable products that could not be isolated in pure form.

13. The same picture arose from an analysis of crude reaction mixtures with 3,5-disubstituted N-arylnitrones.
14. Thermal processes of the same nitrones with methylenecyclopropane gave similar ratios of the products, albeit reaction mixtures were more complex due the presence of regioisomers and open-chain isomers.
