Photoinduced transition-metal- and photosensitizer-free cross-coupling of aryl halides (including Ar–Cl, Ar–Br, and Ar–I) with H-phosphonates (including dialkyl phosphonates and diarylphosphine oxides) is reported. Various functional groups were tolerated, including ester, methoxy, dimethoxy, alkyl, phenyl, trifluoromethyl, and heterocyclic compounds. This simple and green strategy provides a practical
据报道,芳基卤化物(包括Ar–Cl,Ar–Br和Ar–I)与H-膦酸酯(包括二烷基膦酸酯和二芳基膦氧化物)的光诱导无过渡金属和光敏剂交叉偶联。容许各种官能团,包括酯,甲氧基,二甲氧基,烷基,苯基,三氟甲基和杂环化合物。这种简单而绿色的策略提供了合成芳基膦氧化物的实用途径。
