is still largely unknown. Such species displays a bromine-like reactivity toward organic substrates dissolved in CH2Cl2. The observation that styrene, 1-methyl- and 2-methyl styrenes afford, together with dibromo-compounds, appreciable amounts of bromohydrins, suggests that a hypobromite-like species is also formed. Evidence is presented that such a species is a vanadium complex.
在模仿钒依赖性溴过氧化物酶的亲水和疏水部分的两相(H 2 O = CH 2 Cl 2)系统的水相中,通过添加H 2形成单过氧钒络合物(V-BrPO)Ò 2至NH 4 VO 3,氧化溴-到一个物种,其性质在很大程度上仍是未知的。这种物质对溶于CH 2 Cl 2的有机底物表现出类似溴的反应性。苯乙烯,1-甲基和2-甲基苯乙烯与二溴化合物一起提供了可观数量的溴代醇,这一发现表明还形成了次溴酸盐样物质。证据表明这种物质是钒配合物。
