Hoveyda-Grubbs-type systems

The first-generation Hoveyda-Grubbs catalyst decays completely within 4 h in the presence of ethylene in CD2CI2 solutions at 55 C, but its mode of decomposition is not well understood [49]. These types of catalysts are not susceptible to unimolecular degradation involving phosphine attack on the methyiidene, since these systems do not dissociate a phosphine ligand. It is conceivable that... [Pg.332]

Pietrusiewicz and co-workers used optically pure vinylphosphine oxides in the synthesis of substituted derivatives by alkene cross-metathesis (CM), by (achiral) Grubbs and Hoveyda-type ruthenium systems (Scheme 6.47). [Pg.340]
