has been discussed. The distribution of positive charge over the 3-membd. ring and phenyl groups slightly predominates in 6 than in parent annulenone 1, in contrast to 5-cycloheptatrienylidene-2(5H)-thiophenone 5 whose 7-membd. ring is more olefinic than parent tropone 2. Electronic spectrum of 6 exhibits a broad absorption band having a C-T character.
已经合成了标题化合物6,并且已经讨论了将环状π系统插入
二苯基环丙烯酮1中的作用。正电荷在3元膜上的分布。与5-
环庚三烯二烯-2(5H)-
噻吩酮5(其7元)相比,环和苯基在6中比母体
蒽酮1中的稍大。环比母体托酮2的烯烃多。6的电子光谱显示具有CT特性的宽吸收带。
