A cobalt-catalyzed alkene hydroboration with pinacolborane.

Lei Zhang¹, Ziqing Zuo, Xuebing Leng, Zheng Huang.

Abstract

An extremely efficient cobalt catalyst for the hydroboration of both vinylarenes and aliphatic α-olefins with pinacolborane is described, providing the anti-Markovnikov products with excellent regio- and chemoselectivity, broad functional-group tolerance, and high turnover numbers (up to 19,800). The alkene hydroboration route is further extended to a two-step, one-pot hydroboration and cross-coupling of alkylboronates with aryl chlorides.
