已经说明了使用芳基偶氮吡唑连接的邻羟基席夫碱从芳基和杂芳基硼酸合成酚的简单无金属策略。这些可持续的原位羟基化反应时间非常短,使用水性H 2 O 2作为水-醇介质中的氧化剂。目前的方案已被证明对各种富电子和缺电子芳香族底物有效,并提供了对各种酚类的访问。这是首次使用偶氮拉唑连接的希夫碱来增加氧化羟基化反应中H 2 O 2的亲核性。

A compound comprising a ring structure including a ring composed of four carbon atoms and two nitrogen atoms and a substituted or unsubstituted amino group bonded to the ring structure.
The reactions of π-benzoquinone (BQ) with alkylaluminium compounds of the R3Al (R = Et, i-Bu) and RAlCl2 (R = Me, Et, i-Bu) type have been investigated. It was found that hydroquinone and a respective alkylhydroquinone are formed after hydrolysis, from the reaction of BQ with R3Al; hydroquinone and a respective p-alkoxyphenol are formed from reaction of BQ with RAlCl2 (R = Et, i-Bu).

obtained in the reactions of chlorine derivatives of 1,4-benzo-quinone. The results are discussed in terms of a radical mechanism involving a homolytic cleavage of the AlC bond in the donor-acceptor complexformed between the reactants followed by combination of alkyl radicals and aluminium derivatives of semiquinone within a cage. The stable donor-acceptor complexes and aluminium derivative of semiquinone
