We report the first catalytic diborylation of 1,1‐disubstituted vinylarenes with pinacolborane using a cobalt catalyst generated from bench‐stable Co(acac)2 and xantphos. A wide range of 1,1‐disubstituted vinylarenes underwent this transformation to produce the corresponding gem‐bis(boryl)alkanes in modest to high yields. This cobalt‐catalyzed reaction can be readily conducted on a gram scale without the use of a dry box and represents a practical and effective approach to prepare a wide range of branched gem‐bis(boryl)alkanes.

1,1-二取代乙烯基芳烃的钴催化重氮基化:实用的分支的双(双(硼))烷烃的途径。

我们报告了使用从稳定的Co(acac)2和黄药生成的钴催化剂,用频哪醇硼烷进行1,1-二取代的乙烯基芳烃的首次催化重整化反应。宽范围的1,1-二取代的乙烯基芳烃进行此变换,以产生相应的宝石双(硼烷基)烷烃在适度的高产量。这种钴催化的反应可以很容易地以克为单位进行,而无需使用干燥箱,这是一种制备各种支链宝石-双(硼基)烷烃的实用有效的方法。
