hane-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
1- 6-(2-甲基苯甲酰基) - ñ -ethylcarbazole -3-基} -乙烷-1-酮肟ø -乙酸甲酯,极好的双光子光引发剂咔唑,用适中的产率(76.9%)中合成从起始本文中依次进行了N-乙基咔唑的邻甲基苯甲酰化和乙酰化,然后进行了肟化和酯化。通过1 H-NMR,13确认结构。13 C-NMR和IR。借助于一锅法,中和羟胺盐酸盐中和的副产物乙酸可有效地用于酯化反应中。特别地,相转移技术被用于克服由酯化反应中的不均匀反应条件引起的低反应速率的不足。
