Reaction of [Pt(C₂H₄)(PPh₃)₂] with propenoate or 2-methylpropenoate esters gave the complexes [Pt(propenoate)(PPh₃)₂] in good yield. These have been characterised by ¹H, ¹³C, ³¹P and ¹⁹⁵Pt NMR spectroscopy. The complex of benzyl propenoate has been characterised in a diffraction study. Reaction of the complexes produced with tricyclohexylphosphine, PCy₃, gave [Pt(propenoate)(PCy₃)(PPh₃)]. The propenoate complexes were shown to be more stable than those of the 2-methylpropenoates.
