Two-phase dehydrogenation of aryl substituted carbazide compounds
Wang,Ru,Li,Wang,Ma
, p. 1737 - 1742 (1994)
Two-phase dehydrogenation, which is a new reaction of aryl substituted carbazide compounds, is described in this paper. Ten new azo compounds were synthesized by the reaction of aryl substituted carbazide compounds with a phenoxyl radical between two phas
The Synthesis of New Type Bisazo Compounds Using 4-Hydroxy-2,2,6,6-Tetramethyl-1-Piperidinyloxyl as the Phase-Transfer Dehydrogenation Catalyst
Wang, Xiao-Yang,Wang, Yu-Lu,Zhang, Zi-Yi,Li, Jian-Ping,Wang, Cai-Lan
, p. 835 - 837 (1998)
Using 4-hydroxy-2,2,6,6-tetramethyl-l-piperidinyloxyl as the phase-transfer dehydrogenation catalyst to prepare bisazo compounds is reported for the first time. Nine bisaryl carbodiazones were synthesized in high yields under mild conditions. This method

Xiao, Jun-Ping,Wang, Yu-Lu,Jia, Xue-Shun,Wang, Xiao-Yang,Wang, Hong
, p. 1807 - 1812 (2000)
The preparation of bisaryl carbodiazone compounds from the aryl substituted carbazides with Ceric Ammonium Nitrate (CAN) has been reported for the first time in excellent yields (80-91%). This method only needs simple instruments and short reaction time.
Using N-bromosuccinimide and pyridine as the oxidation system to prepare carbonyl and aryl azo compounds
Wang, Yu Lu,Wang, Xiao Yang,Li, Jian Ping,Ma, Dong Lan,Wang, Hong
, p. 1737 - 1742 (2007/10/03)
Using N-bromosuccinimide and pyridine as the oxidation system to dehydrogenate aryl substituted semicarbazide or carbazide to form azo compounds in one phase is described first time in this paper. Nineteen azo compounds have been prepared in excellent yie
