B-Alkylcatecholboranes, prepared by rhodium(I)-catalyzed hydroboration of alkenes, are suitable radical precursors for conjugate addition to activated olefins. This procedure proved to be particularly useful for the control of the regio- and chemoselectivity of such tandem processes. Enantioselective hydroboration has also been successfully coupled with radical chain reaction in a one-pot process.
通过铑(I)催化的烯烃的硼氢化反应制得的B-烷基儿茶酚硼烷是合适的自由基前体,用于共轭加成到活化烯烃上。事实证明,该方法对于控制这种串联过程的区域选择性和化学选择性特别有用。对映选择性硼氢化也已通过一锅法成功地与自由基链反应偶联。
