Benzoyl transfer accompanies the oxidation of monobenzoates of hydroquinones. Oxidising agents used in the present investigation were ceric ion, thallic ion, N-bromosuccinimide, bromine, a high potential quinone, and lithium periodate. Evidence is presented that acylium intermediates are formed in the oxidations with ceric ion: thallic ion oxidations are catalysed by thallous ion, and acyl transfer in these
苯甲酰转移伴随着对苯二酚单苯甲酸酯的氧化。本研究中使用的氧化剂是铈离子、,离子,N-溴琥珀酰亚胺,溴,高电位醌和高碘酸锂。有证据表明,铈离子在铈离子的氧化反应中形成中间体:thallic离子催化Thallic离子氧化,在这些情况下,酰基转移似乎需要溶剂攻击Thallic离子-底物复合物。
