- 1,3-Dithienium and 1,3-Dithiolenium Salts, VI. - N,N-Disubstituted 4-Aminobenzophenones from 1,3-Dithian- and 1,3-Dithiolan-2-ylium Tetrafluoroborates, respectively
-
The 1,3-dithienium- and 1,3-dithiolenium tetrafluoroborates 3 (n =3, 2), respectively, react in good yields with the N,N-dialkylarylamines 4 to give the 2,2-disubstituted cyclic dithio acetals 5, which can be converted after dethioacetalization with HgCl2/HgO into the ketones 7.
