Cp*CoIII-catalyzed C–H allylation of various aromatic C–H bonds usingallylalcohols as allylating reagents is described. Improved reaction conditions using fluorinated alcohol solvents afforded efficient directed C–H allylation of 6-arylpurines, benzamides, and a synthetically useful Weinreb amide with good functional group compatibility.
描述了使用烯丙醇作为烯丙基化试剂的Cp * Co III催化的各种芳香族CH-H键的CH-H烯丙基化。使用氟化醇溶剂改善的反应条件提供了6-芳基嘌呤,苯甲酰胺和具有良好官能团相容性的合成有用的Weinreb酰胺的有效的定向C–H烯丙基化。
