Non-metathetic behavior patterns of Grubbs' carbene

Grubbs' carbene complex [Cl-2(Cy3P)(2)Ru=CHPh] and its second-generation counterpart [Cl-2(Im)(CY3P)Ru=CHPh] have demonstrated remarkable efficiency metathesizing olefins. Furthermore, a growing number of newly discovered catalytic processes mediated by this complex broaden its synthetic utility beyond olefin metathesis. In addition, the ready availability of these stable ruthenium-based catalysts coupled with their tolerance toward a wide variety of common functional groups make Grubbs' catalysts very convenient synthetic tools. This paper presents recent advances in the non-metathetic behavior patterns of Grubbs' carbene.
