Abstract

The reaction of DMF with o-trimethylsilylphenyl triflate in the presence of CsF afforded dimethyldiphenylammonium triflate, xanthene, and xanthone in 62%, 16%, and 24% yields, respectively. On the other hand, the reaction of dimethylthioformamide with triflate and CsF resulted in diphenyl sulfide, xanthene, and xanthone in 62%, 10%, and 12% yields, respectively. The reaction of acetylimidazole with benzyne gave 9-N, N- ...
