- Synthesis and Structure of Phenylazohydroquinones
-
Phenylazohydroquinones 3, 4 (and not hydrazinoquinones) have been synthesized from 2,5-bis(arylamino)-1,4-benzoquinone-3-carboxylic acids 1 and hydrazines 2; the structure of 3 and 4 was confirmed by spectroscopic (IR, UV, 1H-NMR, and 13C-NMR) data.
