Description Pericyclic reaction of cyclohexa-2,4-dienones 8a-c with cycohexa-1,3-diene 2b and cycloheptatriene 5 has been reported. cyclohexadienones react with 2b and 5 to give cycloadducts 9a-c,10a-c and 13a-c,15b,c respectively. Cope rearrangement of the adducts 10a-c and 15b,c to 9a-c and 13b,c, respectively has been described. It has been shown that cyclohexa 2-4-dienones behave as 4 pi component (diene) and they react in a primary inverse demand fashion via pi(4s) (dienone) + pi(2s) (diene/triene) mode.
