Novel phosphitylating reagents containing a phosphorus–fluorine bond and their application in efficient synthesis of phosphorofluoridates and phosphorofluoridothionates
摘要:
包含 P–F 键的新型磷酸化试剂以优异的产率从商业原料中获得。它们在四唑、氯三甲基硅烷或苯甲酰氯的存在下,在中性溶剂中于 20 °C 下与醇反应,生成中间体氟磷酸酯。随后的氧化或硫化处理及保护基团的去除,可得到总产率超过 90% 的氟磷酸酯和硫氟磷酸酯。
