Organoboron "ate" complexes undergo a net vinyl insertion reaction to give 1,1-disubstituted alkenyl boronic esters when treated with stoichiometric allyl acetate and a palladium catalyst. Reactions that employ vinyllithium afforded good to excellent yields after one hour, while reactions that employ vinylmagnesium chloride furnished modest to good yields after 18 hours.
有机硼“配合物”与等摩尔的烯丙基乙酸酯和钯催化剂反应时，会发生净乙烯插入反应，生成 1,1-二取代烯基硼酸酯。采用乙烯基锂的反应在 1 小时后得到了良好到优秀的产率，而采用乙烯基氯化镁的反应在 18 小时后得到了中等至良好的产率。
