ABSTRACT:
Thianthrene in monochlorotoluene, is reacted with excess chlorine in the presence of a Lewis acid catalyst, to yield a mixture of chlorothianthrenes, the major component of which is 2,3,7,8-tetrachlorothianthrene. Recrystallization of the chlorothianthrene mixture from a suitable solvent, such as tetrahydrofuran yields 2,3,7,8-tetrachlorothianthrene of greater than 90 percent purity.
