Tertiary α-hydroxyphosphine oxides have been synthesized via the catalyst- and solvent-free reaction between available secondary phosphine oxides and aliphatic, aromatic and heteroaromatic ketones at 20–62 °C in near to 96–98% yield. The developed method meets the requirements of green chemistry and the PASE (pot, atom, step economy) paradigm. According to quantum-chemical calculations at the B3LYP/6-311++G(d,p) level, the synthesized hydroxyphosphine oxides feature a weak (≈3 kcal·mol–1) O−H···O=P intramolecular hydrogen bond.

仲膦氧化物对酮的无催化剂和无溶剂加氢磷酸化作用:绿色合成的叔α-羟基膦氧化物

叔α-羟基膦氧化物是在20-62°C下通过可用的仲膦氧化物与脂肪族,芳香族和杂芳香族酮之间的无催化剂和无溶剂反应合成的,产率接近96-98%。所开发的方法符合绿色化学和PASE(锅,原子,阶梯经济)范式的要求。根据在B3LYP / 6-311 ++ G(d,p)水平上的量子化学计算,合成的羟基膦氧化物具有弱的(≈3kcal·mol –1)OH···O = P分子内氢键。
