chemical oxidants and metal catalysts, an aqueous electrochemical synthesis of 5-trifluoromethyluracil in batch and continuous flow was reported. The green and economically friendly approach employing commercially available CF3SO2Na as a CF3 source and cheap (NH4)2SO4 as a supporting electrolyte afforded the 5-trifluoromethyluracil in 10 g scale in batch electrolysis. The continuous flow-electrolysis
据报道,在不使用化学氧化剂和金属催化剂的情况下,以间歇和连续流动方式水相电化学合成 5-三氟甲基尿嘧啶。采用市售的CF 3 SO 2 Na作为CF 3源和廉价的(NH 4 ) 2 SO 4作为支持电解质的绿色且经济友好的方法在间歇电解中提供了10g规模的5-三氟甲基尿嘧啶。采用连续流动电解技术进一步促进5-三氟甲基尿嘧啶的放大合成。

perfluoroalkyl motifs in the core structure, access to such analogues typically requires multi-step synthesis. Here, we report a mild, metal-free and operationally simple strategy for the direct perfluoroalkylation of uracils, cytosines and pyridinones through a visible-light induced pathway from perfluoroalkyl iodides. This photochemical transformation features synthetic simplicity, mild reaction
