The first metal-free and facile radical addition/cyclization of simple alcohols with diaryl(arylethynyl)phosphine oxides has been described with azobisisobutyronitrile as a radical initiator, affording an efficient and one-pot procedure to access a new class of hydroxymethyl benzo[]phosphole oxides and 6-indeno[2,1-]phosphindole 5-oxides for potential application in organic materials via sequential C(sp)-H/C(sp)-H functionalization. The method employs easily accessible starting materials and is endowed with high regioselectivity and broad functional-group tolerance.
以偶氮二异丁腈为自由基引发剂，首次报道了简单醇与二芳基（芳基乙炔基）氧化膦的无金属且简便的自由基加成/环化反应，通过连续的C(sp)-H/C(sp)-H官能团化反应，提供了一种高效的一锅法来合成一类新型的羟甲基苯并[]氧化膦和6-茚并[2,1-]磷杂吲哚5-氧化物，这些化合物在有机材料中具有潜在应用价值。该方法使用易于获得的起始原料，具有高区域选择性和广泛的官能团耐受性。
