Abstract

The catalytically active propagating species involved in the self-metathesis of ethyl oleate obtained from the multi-component Noels' catalytic system {[RuCl₂(p-cymene)(PCy₃)] + Me ₃SiCHN₂} are probably the same as those of the single-component well-defined Grubbs' 1st generation catalyst, [Cl ₂Ru=CHPh(PCy₃)₂] (1-Ph). In the case of the Noels' catalyst, it involves the de-coordination of p-cymene, and the redistribution of PCy₃ ligands to generate only 5-10% of [Cl ₂Ru=CHR(PCy₃)₂], where R = CH-(CH ₂)₆-CH₃ (1-Oct) and R = CH-(CH ₂)₆-COOEt (1-E), while 1-Ph can generate 100% of these species.
