Aroyl group driven phosphonate-phosphate rearrangement in dialkyl/aryl(α-hydroxy-β-oxo-β-arylethyl)phosphonates having α-proton under basic conditions is presented and extended to a novel one-pot direct coupling method between 2-oxoaldehydes (2OA) and H-phosphonates/diphenylphosphine oxide. The one-pot coupling reaction has an advantage in terms of using commercially available substrates and its broad substrate scope. The reactions between 2OAs and diphenylphosphine oxide represent a unique phosphine oxide-phosphinate rearrangement.

芳酰基驱动的[1,2]膦酸酯-磷酸酯/氧化膦-次膦酸酯重排

提出了在碱性条件下具有α质子的二烷基/芳基（α-羟基-β-氧代-β-芳基乙基）膦酸酯中由芳酰基驱动的膦酸酯-磷酸盐重排，并将其扩展为2-氧代醛之间的新型一锅直接偶联方法2OA）和H-膦酸酯/二苯基膦氧化物。一锅耦合反应在使用可商购的基板及其广泛的基板范围方面具有优势。2OA与二苯基膦氧化物之间的反应代表独特的氧化膦次膦酸酯重排。
