含有两个不稳定膦配体的络合物Ia是含有活化NHC配体和不稳定膦供体的重要类别的烯烃复分解催化剂的通用前体。剩余的PPh 3配体的不稳定性也可以允许通过IMes二取代;这种副反应很容易通过精确的化学计量控制来防止。
Complex la, containing two labile phosphine ligands, is a versatile precursor to the important class of olefin metathesis catalysts containing an activating NHC ligand and a labile phosphine donor. The lability of the remaining PPh3 ligand can also permit disubstitution by IMes; this side reaction is easily prevented by precise stoichiometric control.
