On irradiation in benzene solution in the presence of air or iodine, 1,6-dimethyl-1,6-dimethyl-1,6-diphenylhexa-1,3,5-triene is converted into 6,12-dimethylchrysene. Under the same conditions 3-methyl-1,6-diphenylhexatriene gives chrysene, by ejection of the methyl group, but 1,3,6-triphenylhexatriene unexpectedly cyclises to 1,2,4-triphenylbenzene.
在空气或碘的存在下在苯溶液中辐照时,将1,6-二甲基-1,6-二甲基-1,6-二苯基六-1,3,5-三烯转化为6,12-二甲基ch。在相同条件下,3-甲基-1,6-二苯基己三烯通过喷射甲基基团而得到苯,但是1,3,6-三苯基己三烯意外地环化为1,2,4-三苯基苯。
