[反应：开发了一种使用芳基重氮离子的高效催化硼化方法，该方法使用原位形成的卡宾-钯催化剂来得到芳基频哪醇合硼烷产物。在不加碱的情况下获得了用作由双（2，6-二异丙基苯基）-4，5-二氢咪唑鎓氯化物形成的催化剂的N-杂环卡宾-钯络合物的X射线结构。
[reaction: see text] A highly efficient catalytic borylation process with aryldiazonium ions was developed using a carbene-palladium catalyst formed in situ to give arylpinacolatoborane products. An X-ray structure for the N-heterocyclic carbene-palladium complex, used as the catalyst formed from bis(2,6-diisopropylphenyl)-4,5-dihydroimidazolium chloride, was obtained without added base.
