OXIDATIVE CLEAVAGE OF THE C-C BOND IN PROCESSES INVOLVING THE HETEROAROMATIZATION OF 9R-sym-NONAHYDRO-10-OXA(CHALCOGENA)ANTHRACENES

Article abstract of DOI:10.1007/BF00476199

The reaction of 9-(2-methoxyphenyl)- and 9-(2-thienyl)-sym-nonahydro-10-selena(thia)anthracenes with trifluoroacetic acid causes their heteroaromatization with the elimination of substituents from the γ positions of the heterorings.A similar transformatio
