Abstract

111 atom 5. At the same time positions 2 and 7 are para to the sulfur atoms 5 and 10, respectively. Thus, two products of dibromination, 2, 7-and 2, 8-dibromothianthrene, are possible with thianthrene. Attempts to separate the mixture into the two isomers through oxidation to the tetraoxides and subsequent recrystallizations were unsuccessful. The reductive chlorination of 10-methylphenothiazined-oxide with hydrochloric acid to give 3- ...
