In this work, we developed the catalytic guanylation of thiourea using Ru(bpy)3Cl2 as a photocatalyst under irradiation by visible light. The conversion of various thioureas to the corresponding guanidines was achieved using 1–5 mol % of photocatalyst in a mixture of water and ethanol at room temperature. Key benefits of this reaction include the use of photoredox catalyst, low-toxicity solvents/base
在这项工作中,我们开发了Ru(bpy)3 Cl 2作为光催化剂在可见光照射下硫脲的催化鸟嘌呤化。在室温下,在水和乙醇的混合物中使用1-5 mol%的光催化剂,可以将各种硫脲转化为相应的胍。该反应的主要优点包括使用光氧化还原催化剂,低毒性溶剂/碱,环境温度和开放式烧瓶环境。
