Abstract

High-spin products of photolysis of 1,3,5-triazido-2,4,6-trichlorobenzene in a 2-methyltetrahydrofuran solution frozen at 6 K has been studied using EPR spectroscopy in combination with quantum-chemical calculations. It has been found that the photolysis of this triazide leads to the formation of a mixture of triplet 1,3-diazido-2,4,6-trichlorophenyl-5-nitrene, quintet 1-azido-2,4,6-trichlorophenyl-3,5-dinitrene, and septet 2,4,6-trichlorophenyl-1,3,5-trinitrene. The solvent effect on the EPR spectra and the magnetic characteristics of nitrenes has been studied.

摘要

使用 EPR 光谱结合量子化学计算研究了 1,3,5-三叠氮基-2,4,6-三氯苯在 6 K 冷冻的 2-甲基四氢呋喃溶液中光解的高自旋产物。已发现该三叠氮化物的光解导致形成三重态1,3-二叠氮基-2,4,6-三氯苯基-5-氮烯、五重态1-叠氮基-2,4,6-三氯苯基-3,5-二硝基和七重态2,4,6-三氯苯基-1,3,5-三氮烯的混合物。研究了溶剂对 EPR 光谱和氮宾磁性特性的影响。
