Notizen:
Both C-(2-methylphenyl)-N-phenyl and C-(3-methylphenyl)-N-phenyl nitrones (1a, b) reacted with N-phenylmaleinimide and fumaronitrile to give the normal primary cycloadducts. The reaction of the two nitrones (1a, b) with 4-phenyl-1,2,4-triazoline-3,5-dione and diacetylacetylene afforded rearrangement products. The unexpected 1,3,4-oxadiazolidin-2-ones were isolated from reaction with phenylisocyanate. In contrast, tetracyanoethylene forms charge-transfer complexes with both nitrones instead of cycloaddition products. The structural elucidation of the reaction products was made on the bases of the elemental analysis as well as i.r. and 1H-n.m.r. spectral data.
