Various salts of 1,3-benzodithiolylium ion were prepared in excellent yields on treatment of 2-alkoxy- and 2-alkylthio-1,3-benzodithioles with acids in acetic anhydride. The reactions of 1,3-benzodithiolylium tetrafluoroborate (<B>1a</B>) with a wide variety of nucleophilic reagents (alcohols, water, thiols, hydrogen sulfide, primary, secondary, and tertiary amines, ammonia, <I>N</I>,<I>N</I>-dimethylformamide, electron-rich aromatic compounds, active methylene compounds, tropilidene, and sodium borohydride) were studied. In all cases examined, <B>1a</B> reacted with nucleophilic reagents at the 2-position to give the corresponding 1,3-benzodithioles in good yields, excepting the reactions with tertiary amines and <I>N</I>,<I>N</I>-dimethylformamide which resulted in the formation of dibenzotetrathiafulvalene. Salt <B>1a</B> was also prepared from 1,3-benzodithiole and trityl tetrafluoroborate.
