摘要
(Bu 4N)2[ReBr6]在暴露于空气中的乙基溴中的溶液在254或313 nm处照射可使六溴间酚酸盐(IV)完全转化为过氢酸盐离子。反应速率线性依赖于入射光强度和铼络合物吸收的光的比例与溴乙基吸收的光的比例的组合。实验结果与溶剂引发和金属引发两种途径产生的过氧自由基CH 3CH(Br)OO通过电子转移氧化[ReBr 6]2−的机理一致。
The Photooxidation of Hexabromorhenate(IV) in Ethyl Bromide
Irradiation at 254 or 313 nm of solutions of (Bu 4N)2[ReBr6] in ethyl bromide exposed to air causes complete conversion of the hexabromorhenate(IV) to perrhenate ion. The rate of the reaction is linearly dependent on the incident light intensity and on a combination of the fraction of light absorbed by the rhenium complex and the fraction absorbed by the ethyl bromide. The experimental results are consistent with a mechanism in which the peroxy radical CH 3CH(Br)OO, produced in both the solvent-initiated and metal-initiated pathways, oxidizes [ReBr 6]2− by electron transfer.
