| Abstract: | A convenient method using FeCl3 as oxidant to dehydrogenate symmetric hydrazo compounds is reported for the first time. The method is superior to other known methods for dehydrogenating ArNHNHAr. It needs only cheap and less toxic reagents, mild conditions and short reaction time. Eight symmetric azo compounds are prepared in good yields. |
