developed and it allows the regiospecific introduction of allyl residues to benzoic acids. In the presence of a [Ru(p‐cymene)Cl2]2 and K3PO4, benzoic acids react with allyl acetates at only 50 °C to give the corresponding ortho‐allylbenzoic acids. The protocol is generally applicable to both electron‐rich and electron‐poor benzoic acids in combination with linear and branched allyl acetates. The products
已经开发出了一种羧酸盐定向的邻-CH功能基,可以将烯丙基残基的区域特异性引入苯甲酸中。在[Ru(p- cymene)Cl 2 ] 2和K 3 PO 4存在下,苯甲酸在仅50°C的条件下与乙酸烯丙酯反应,生成相应的邻-烯丙基苯甲酸。该方案通常适用于富电子和贫电子的苯甲酸与直链和支链乙酸烯丙酯的组合。可以通过双键迁移,内酯化或脱羧等方法在原位进一步对产品进行功能化。
