Abstract

The highest initiation rate of any reported ruthenium-based catalyst was found for the new olefin-metathesis catalyst [(H₂IMes)(3-Br-py)₂(Cl)₂RuCHPh] (1), which was synthesized in one step from commercially available reagents. Complex 1 is highly efficient for the cross metathesis of acrylonitrile, which is generally a poor substrate for metathesis reactions (e.g., see scheme). Mes=2,4,6-trimethylphenyl.

一种实用的高活性钌基催化剂对丙烯腈交叉复分解的影响

钌基催化剂中引发率最高的是新型烯烃复分解催化剂[(H2IMes)(3-Br-py)2(Cl)2Ru CHPh](1)，该催化剂由市售试剂一步合成。配合物1对丙烯腈的交叉复分解非常有效，而丙烯腈通常是复分解反应的不良底物(例如，见图)。Mes = 2, 4, 6-trimethylphenyl。
