The thermal reaction of (Z)-2,3-diphenyl-2-(2,3-diphenyl-3-oxo-1-propenyl)-2H-azirine with [Mo(CO)6] or [Mo(CO)3(MeCN)3] was reinvestigated to afford 2,3,5,6-tetraphenylpyridine along with the pyrroles and 1,3-oxazepine derivative. The formation of 1,3-oxazepine was demonstrated to be the purely thermal process. The 1,2,4,5-tetraphenyl-5-oxo-1,3-pentadienylnitrene complex was shown to give the pyridine and the pyrrole derivatives.
