The conversion of esters and ketones into easily dehydrated α-silylated alcohols, and protodesilylation of the resultant vinylsilanes, gives alkenes under relatively mild acidic conditions.

A Pd-catalyzedregioselectivehydroesterification of alkyl terminal olefins with aryl formates is described. A wide variety of linear carboxylic esters bearing various functional groups can be obtained in good yields with high regioselectivities under mild reaction conditions by using 1,2-DTBPMB or (p-F-Ph)3P as ligand. The reaction process is operationally simple and requires no handling of toxic
描述了烷基末端烯烃与甲酸芳基酯的 Pd 催化区域选择性加氢酯化反应。以1,2-DTBPMB或( p -F-Ph) 3 P为配体,在温和的反应条件下,可以高产率、高区域选择性地获得多种带有各种官能团的直链羧酸酯。该反应过程操作简单,不需要处理有毒的CO或强酸。所得芳基酯可以容易地转化为其他羧酸衍生物。
