The mass spectral fragmentation patterns of ten 7‐( o ‐ and p ‐R‐benzylidene)‐3‐( o ‐ and p ‐R‐phenyl)‐3,3a,4,5,6,7‐hexahydro‐2 H ‐indazoles, I, obtained by electron impact have been studied. All the spectra analyzed contain molecular ions and the principal fragmentation routes take place either from the molecular ion, or from (M + ‐1) ion. Likewise, our investigation of the mass spectra of these compounds revealed interesting relationships between the substitution pattern in the framework of I and the fragmenation pathways.
