Abstract

Numerous examples of benzo[c]thiophene 1 ( Fig. 1) and its analogs 7 are known in the literature. However, to our knowledge, there are no reports on benzo[c]thiophene derivatives capped with fluorene. In continuation of our work on benzo[c]thiophenes, 8 we report here our preliminary results on the synthesis and characterization of 9,9-dialkylfluorene capped benzo[c]thiophenes/benzo[c]selenophenes. ... Friedel–Crafts phthaloylation of 9,9- ...
