## Abstract Different photochemical behavior between 3,6β and 2,5βdiβ__t__βbutylβ3__H__βazepine was observed. The former gave wavelength dependent products 3,5βdiβ__t__βbutylpyridine on irradiation through Pyrex filter __via__ photolysis and 4,7βdiβ__t__βbutylβ2βazabicyclo[3.2.0]heptaβ2,6βdiene on
A New Ring Contraction Rearrangement of 2,5-and 3,6-Di-tertbutyl-3H-azepines to Pyridine Derivatives. -A novel ring contraction reaction of di-tert-butyl-substituted 3H-azepines furnishing pyridine derivatives under bromination conditions is described. A plausible mechanism for the rearrangement via
