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 4π component (diene)
已经报道了环己-2,4-二烯酮8a-c与环己-1,3-二烯2b和环庚三烯5的周环反应。环己二酮与2b和5反应,分别得到环加合物9a-c,10a-c和13a-c,15b,c。已经描述了加合物10a-c和15b,c至9a-c和13b,c的应对重排。它已经表明,环己2-4二烯酮表现为4π成分(二烯)和它们在主逆需求的方式通过反应π 4小号(二烯酮)+ π 2s(二烯/三烯)模式。
