The complex H2Ru(PPh3)4 reacts with methyl acrylate to give bis(methylacrylate)bis(triphenylphosphane)ruthenium(0).Temperature-dependent NMR spectra show that the complex exists in two isomeric forms in solution.The major form (ca. 74percent) has one methyl acrylate ligand η²-coordinated and the other η⁴-coordinated as a 1-oxabutadiene ligand.This complex reacts with water to give the monoaqua adduct, the crystal structure of which is reported.
