Green synthesis method of carbazole oxime ester photoinitiator

The invention discloses a green synthesis method of a carbazole oxime ester photoinitiator. According to the method, N-ethyl carbazole is taken as the raw material; then N-ethyl carbazole carries out condensation reactions with o-toluoyl chloride and acetic anhydride/acetyl chloride in the presence of a zirconium catalyst, and finally the condensation reaction product is oximated and esterified to obtain the carbazole oxime ester photoinitiator. The synthesis method does not need high temperature and high pressure, the conditions are mild, and thus the synthesis method is very safe. During the synthesis process, a zirconium catalyst is used, no aluminum chloride or zinc wastewater is generated therefore, the generated byproducts can be recovered, moreover, no solvent that is harmful to the environment is used, and the synthesis method is environment-friendly and is suitable for industrial production.

Synthesis of 1-{6-(2-methylbenzoyl)-N-ethylcarbazole- 3-yl}-ethane-1-one oxime O-acetate

1-{6-(2-Methylbenzoyl)-N-ethylcarbazole-3-yl}-ethane-1-one oxime O-acetate, an excellent two-photon carbazole photoinitiator, was synthesized with moderate yield (76.9%) starting from the successive o-methyl benzoylation and acetylation of N-ethylcarbazole, followed by oximation and esterification in the article. The structure was confirmed by 1H-NMR, 13C-NMR, and IR. The by-product acetic acid in the neutralization of hydroxylamine hydrochloride is effectively utilized in esterification with the aid of the one-pot process. In particular, the phase transfer technique is applied to overcome the deficiency of low reaction rate caused by heterogeneous reaction conditions in esterification.
