摘要

Reaction of phenyl (3-thieny1) glycolic acid (1) with A1C13 in benzene solution leads to the formation of 4H-indeno [1, 2-b] thiophene4-carboxylic acid (2) whereas analogous reaction of phenyl@-thieny1) glycolic acid (4) produces no indenothiophene but only a mixture of 5 and 6. In the case of di-(24hienyl) glycolic acid (14b) and di43-thieny1) glycolic acid (16b) analogous results are obtained, with the former leading to the formation of 15 and the ...
