We report the C-H alkylation of biarylphosphines at the ortho' position(s) with alkenes by using rhodium(I) catalysis, which provides straightforward access to a large library of multifunctionalized phosphines. Some of these modified ligands outperformed commercially available phosphines in the Pd-catalyzed carboxylation of aryl bromides with carbon dioxide in the presence of a photoredox catalyst.
我们报道了通过铑（I）催化实现联芳基膦在邻位与烯烃的C-H烷基化反应，该反应为大量多功能化膦的合成提供了直接途径。在光氧化还原催化剂存在下，一些这些修饰后的配体在钯催化的芳基溴与二氧化碳的羧化反应中表现优于市售膦。
