The reactions of tropolones with tetrasulfur tetranitride gave 4H-cyclohepta[c][1,2,5]thiadiazol-4-ones, 6H-cyclohepta[c][1,2,5]thiadiazol-6-one, and 7H-cyclohepta[1,2-c: 3,4-c′]bis[1,2,5]thiadiazol-7-ones (9–56% yields) in one step. The yields of the products were not improved so much under high pressure and by the addition of a radical initiator.
