Process for the preparation of nitrosobenzenes

摘要

Preparation of nitrosobenzene in a high yield comprises oxidizing aromatic amines in an inert organic solvent(s) with hydrogen peroxide using sodium molybdate dihydrate in a mol. ratio of aromatic amines to H2O2 to NaMo2H of 1:2-5:0.001-0.05. Preparation of nitrosobenzene of formula (I) comprises oxidizing aromatic amines in an inert organic solvent(s) with hydrogen peroxide using sodium molybdate dihydrate (NaMo2H) at 5-25 degrees C in a molar ratio of aromatic amines to H2O2 to NaMo2H of 1:2-5:0.001-0.05. R<1> and R<2> = H or 1-4C alkyl or alkoxy.
