Cross-Hetero-Dehydrogenative Coupling Reaction of Phosphites: A Catalytic Metal-Free Phosphorylation of Amines and Alcohols
Phosphorylation of amines, alcohols, and sulfoximines are accomplished using molecular iodine as a catalyst and H2O2 as the sole oxidant under mild reaction conditions. This method provides an easy route for synthesizing a variety of phosphoramidates, phosphorus triesters and sulfoximine-derived phosphoramidates which are of biological importance.
在温和的反应条件下,使用分子碘作为催化剂并使用H 2 O 2作为唯一的氧化剂,可以实现胺,醇和亚磺酰亚胺的磷酸化。该方法提供了一种容易的途径,用于合成具有生物学重要性的多种氨基磷酸酯,三酯磷和源自亚磺酰亚胺的氨基磷酸酯。

Metal‐Free Site‐Selective Direct Oxidative Phosphorylation of Pyrazolones
established under metal-free direct oxidative coupling processes. A reaction between pyrazolones and secondary phosphonates in the presence of TBAI/TBHP combination could result in the N−P bond formation at N2 position. Meanwhile, the C−P bond coupling at C3 position could be obtained from a reaction of N2-substituted pyrazolone substrates with secondary phosphine oxides using Selectfluor. These chemo- and
