摘要

Phosphine–copper (I) complexes efficiently catalyzed the mono-boration of electron- deficient alkynes in the presence of MeOH and also catalyzed conjugate reductions of alkenylboronates bearing an electron-withdrawing group. The mono-addition of bis (pinacolato) diboron to alkynes catalyzed by a copper–Xantphos complex produced vinylboronates with high regio and stereoselectivity and asymmetric reduction of the ...
