An efficient oxidative carbocyclization/borylation of enallenes uses Pd(OAc)2 as the catalyst, B2pin2 as the boron‐transfer reagent, and 1,4‐benzoquinone (BQ) as the oxidant (see scheme). The reaction seems to take place through activation of the allene by a PdII complex to give an alkenyl–PdII intermediate followed by carbopalladation of the olefin and subsequent cleavage of the intermediate palladium–carbon
一种有效的氧化enallenes的carbocyclization /硼基化使用的Pd(OAC)2作为催化剂,B 2销2作为硼转移试剂,和1,4-苯醌(BQ)作为氧化剂(参见方案)。该反应似乎是通过Pd II络合物活化丙二烯生成链烯基-Pd II中间体,然后烯烃进行碳钯催化,随后硼试剂裂解中间的钯-碳键而发生的。
