Urea and thiourea formed relatively stable liquid deep eutectic mixtures with KOH at certain ratios. These mixtures showed high activity in the reaction with benzils, quickly forming hydantoins and thiohydantoins in high yields.
尿素和硫脲与KOH按一定比例形成相对稳定的液体低共熔混合物。这些混合物在与苯偶酰的反应中表现出高活性,快速形成高产率的乙内酰脲和硫代乙内酰脲。
