investigated under basic and acidic media. It was demonstrated that the real phosphorylating agent involved in the reaction was phosphane (PH3) in basic media, and hypophosphorous acid (H3PO2) in acidic media. A convenient one-pot synthesis of (α-hydroxyalkyl)phosphinic acids from red phosphorus and aldehydes in basic media was realized under sonication. The same reaction under acidic media in the presence
在碱性和酸性介质下研究了红磷对醛的反应性。结果表明,参与反应的真正磷酸化剂是碱性介质中的磷烷(PH3)和酸性介质中的次磷酸(H3PO2)。在超声处理下,从红磷和醛在碱性介质中方便地一锅合成(α-羟烷基)次膦酸。在氢碘酸存在下在酸性介质下的相同反应产生相应的膦酸。(α-羟烷基)次膦酸在催化量的盐酸存在下,在次磷酸和醛的超声处理下很容易制备。
