POLYCYCLIC ARENE SULFIDES - PREPARATION OF A 1A,2,3,11B-TETRAHYDROBENZ[5,6]ANTHRA[1,2-B]THIIRENE, 6B,7A,8,9-TETRAHYDROBENZO[10,11]CHRYSENO[1,2-B]THIIRENE, AND 7,8,8A,9A-TETRAHYDROBENZO[10,11]CHRYSENO[3,4-B]THIIRENE

摘要

The title compounds 5, 7 and 9 which are the first arene sulfides of 7,8-dihydrobenz[a]anthracene, 8,9- and 10,11-dihydrobenzo[a]pyrene, respectively, have been synthesized by treatment of the corresponding arene oxides 4, 6 and 8 with N,N-dimethylthioformamide in the presence of catalytic amounts of trifluoroacetic acid.
