ResumoA reinvestigation of the reactions of nitrosobenzene with diethyl methylenemalonate and 1,1-diphenylethylene has shown that the products obtained are N-phenyl-N-(β,β-dicarbethoxyvinyl)-hydroxylamine and α,α,N-triphenylnitrone, respectively. These findings refute the previous assignments (Ingold, 1924) of 1,2-oxazetidine ring structures for these products. Proofs of structure were based upon IR, UV and PMR spectroscopy in addition to degradation and reduction studies.
