  Benzotris- (3) and benzobis[1,2,5]thiadiazole (4) were prepared in a moderate yield, respectively, by the reaction of tetrasulfur tetranitride (5) with halocatechols (6) and -resorcinols (7). The reduction of 3 and 4 with Sn powder in a mixture of concentrated hydrochloric acid and dioxane gave benzenehexamine (1) and 1,2,3,4-benzenetetramine (2a) and its 5-methyl derivative (2b) in good yields, as

  The reaction of cyclohexanones with copper(II) bromide gave polybrominated cyclohexanediones in all cases except for the case of 3,5-dimethylcyclohexanone. Moreover, in this reaction, a pyrocatechol and a phenol derivative were obtained from 4-methyl- and 3,5-dimethylcyclohexanone respectively. The mechanism of this reaction was discussed.
