The coupling of methylene and vinyl ligands at a ruthenium(II) centre
Abstract
The reaction of [Ru(CHCH2)Cl(CO)(PPh3)2] with diazomethane provides the allyl complex [Ru(η3-CH2CHCH2)Cl(CO)(PPh3)2] which is also the product of the reactions of [RuHCl(CO)(PPh3)3] with either allene or propyne and which reacts subsequently with NaS2CNMe2 to provide [RuH(S2CNMe2)(CO)(PPh3)2] and allene.
