A new reactibn involving carbon-carbon bond cleavage of the aziridine ring has been observed. Refluxing of 1, 2, J-triphenylaziridine(') (I) with diethylacetylene dicarboxylate in toluene for eleven hours forms 1,2,5-triphenyl-3,4-dicarbethoxy-3-pyrroline(II) in 98% vield. I Recrystallization from e
As with the symmetrical, acyclic vicinal-diones previously investigated', the photocyclizations of these substances give predominantly 2-hydroxycyclobutanones. Further mechanism studies have shown that the triplet state gives this reaction since it is photosensitized by benzophenone, and that with
