A Pd-catalyzed regioselective hydrocarboxylation of alkyl terminal olefins with oxalic acid is described. A wide variety of linear carboxylic acids can be readily obtained in good yields and high l/b (linear/branched) ratios with Pd2(dba)3 and (p-ClPh)3P under mild conditions. The reaction process is operationally simple and requires no handling of toxic CO. In addition, branched carboxylic acids can
描述了 Pd 催化的烷基末端烯烃与草酸的区域选择性加氢羧化反应。在温和条件下,使用 Pd 2 (dba) 3和 ( p -ClPh) 3 P,可以容易地以良好的收率和高 l/b(直链/支链)比率获得多种直链羧酸。该反应过程操作简单,不需要处理有毒的CO。此外,还可以与PdCl 2和(2',6'-二甲氧基-[1,1'-联苯]-2)以良好的区域选择性形成支链羧酸。 -基)二苯基膦( L1 )。
