A number of chloro-, methyl- and methoxy-substituted azobenzenes have been reduced to the corresponding hydrazines by using an aqueous solution of Na 2S2O4. The yield is generally excellent, but two compounds, viz. 4,4-dimethoxyazobenzene and 2,2,4,4,6,6- hexamethylazobenzene, gave no hydrazine at all. Georg Thieme Verlag Stuttgart.
