Hydrophosphination of CO2 with 1,3,2‐Diazaphospholene (NHP‐H; 1) afforded phosphorus formate (NHP‐OCOH; 2) through the formation of a bond between the electrophilic phosphorus atom in 1 and the oxygen atom from CO2, along with hydride transfer to the carbon atom of CO2. Transfer of the formate from 2 to Ph2SiH2 produced Ph2Si(OCHO)2 (3) in a reaction that could be carried out in a catalytic manner
通过1,3,2-二氮杂膦烯(NHP-H; 1)对CO 2进行氢磷酸化,通过1中的亲电磷原子与CO 2中的氧原子之间的键形成甲酸磷(NHP-OCOH; 2),与氢化物一起转移到CO 2的碳原子上。将甲酸酯从2转移到Ph 2 SiH 2可以在反应中生成Ph 2 Si(OCHO)2(3),该反应可以通过使用5 mol%的1进行催化。这些基本反应用于在环境条件下在一锅中用CO 2对胺衍生物进行无金属催化的N-甲酰化反应。
