Bis(allyl)nickel is an organonickel compound with the formula Ni(η3-C3H5)2. The molecule consists of two allyl ligands bound to nickel(II). It has inversion symmetry. [1] It is a volatile yellow liquid at room temperature.
It can be prepared by the reaction of allyl magnesium bromide with anhydrous nickel chloride. [2] It was first prepared similarly by Gunther Wilke et al. The same group reported that the complex react with carbon monoxide to give nickel tetracarbonyl and 1,5-hexadiene. It catalyzes the trimerization of butadiene. [3] With tertiary phosphines, the complex gives the tetrakis derivative. Such reactions to proceed via the intermediacy of the 18-electron adduct. [4]
