碩士 === 國立中山大學 === 化學系研究所 === 97 === 一.Pyrolysis of 2-(N,N-dimethylamino)styrylarenes (29a-e) and 2-(N,N- benzylmethylamino)styrylarenes (30a-f) both gave 2-(ar-2-yl)- benzo[b]arenes 35a-f, 39a-e, their isomers 36a-e, 40a-e and the other products. On the other hand, photolysis of 29a-e gave electrocyclic products 2, 57b-e and 22a-e, respectively. However photolysis of 30a-f only gave the complicated and unknown compounds. 二.Pyrolysis of benzoic 1,3-dimethyl-2-indolyl anhydride (54) gave (1,3-dimethylindol-2-yl)phenylmethanone (63), 1,3-dimethylindole (65) and bis(1,3-dimethylindol-2-yl)methanone (66) as the main products.
