Conclusions

  1. 1.

    Mass spectroscopy has been used to obtain definite structures for the photocyclo-adducts of cyclo-pentanone and cyclohexanone with monosubstituted acetylene derivatives.

     
  2. 2.

    Principal fragmentation patterns have been developed for the 7-alkyl- (Ia-c), 6-alkyl- (IIa-c), and 1-alkyl- (IIIa-c) substituted bicyclo[3.2.0]hept-6-en-2-ones; it is suggested that the molecular ions of (IIa-c) and (IIIa-c) undergo a (IIa-c) ⇌ (IIIa-c) interconversion in the photoexcited state.
