Ionic liquids are used in various fields due to their unique physical properties and are widely utilized as reaction solvents in the field of synthetic organic chemistry. We have previously proposed a new organic synthetic method in which the catalyst and reaction reagents are supported on ionic liquids. This method has various advantages, such as the ability to reuse the reaction solvent and catalyst and its facile post-reaction treatment. In this paper, we describe the synthesis of an ionic liquid-supported anthraquinone photocatalyst and the synthesis of benzoic acid derivatives using this system. This synthesis of benzoic acid derivatives via the cleavage of vicinal diols by an ionic liquid-supported anthraquinone photocatalyst is an environmentally friendly process, and furthermore, it has a simple post-reaction process, and the catalyst and solvent can both be reused. To the best of our knowledge, this is the first report on the synthesis of benzoic-acid derivatives via the cleavage of vicinal diols using light and an ionic-liquid-supported catalyst.
离子液体由于其独特的物理性质而在各个领域得到广泛应用，并被广泛用作合成有机化学领域的反应溶剂。我们之前提出了一种新的有机合成方法，其中催化剂和反应试剂负载在离子液体上。该方法具有许多优点，例如能够重复使用反应溶剂和催化剂，以及易于进行后反应处理。本文描述了一种离子液体负载的蒽醌光催化剂的合成方法，以及利用该体系合成苯甲酸衍生物的方法。通过离子液体负载的蒽醌光催化剂催化邻二醇断裂来合成苯甲酸衍生物是一种环保的过程，此外，该过程具有简单的后反应处理步骤，催化剂和溶剂都可以重复使用。据我们所知，这是首次用光和离子液体负载催化剂来合成邻二醇断裂生成苯甲酸衍生物的报道。
