cis- And trans-N-Nitroso-2,4-diphenylazetidines

Powell, Burwell F.,Reichenthal, Jules,Overberger, C. G.,Anselme, J.-P.

, p. 219 - 224 (2007/10/02)

The synthesis of cis- and trans-2,4-diphenylazetidines as well as that of their N-nitroso derivatives is described.The "abnormal" reduction of the N-nitrosamines gives a cis-trans mixture of the expected 1,2-diphenylcyclopropanes.However, no stereochemical correlations could be made owing to the base-induced isomerisation of the starting N-nitrosamines during the course of the reaction.
