A Convenient Method for Dehydrogenation of Symmetric Hydrazo Compounds
摘要:
A convenient method using FeCl3 as oxidant to dehydrogenate symmetric hydrate 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 ate compounds are prepared in good yields.
