The exchange of the PCy3 ligand in complex 2 by an o-isopropyl-phenylether ligand leads to the extremely stable and highly selective initiator 3 for cross metathesis reactions. For the first time, Ru-catalysed cross coupling with acrylonitrile can be performed in good yields.

Cross-couplingreactionsbetween two alkenes, leading to newfunctionalisedalkenes, can be brought about via‘hydrocobaltation’ of one of the alkenes followed by irradiation of the resulting organocobalt reagent in the presence of the second alkene substrate.
