Monoolefin complexes M(CO)3(R2PC2H4PR2)(ol) (M = Cr, Mo, W; R = CH3, C6H5; ol = maleic anhydride, dimethyl fumarate, dimethyl maleate, methyl acrylate, ethylene, styrene, norbornene) are obtained photochemically from the tetracarbonyl chelate phosphane derivatives.Facial complexes are formed primarily, some of which rearrange intramolecularly to the meridional isomers.The substitution of the olefin proceeds via a dissociative mechanism, the meridional isomers rearrange back to the facial ones prior to the rupture of the metal-olefin bond.
