Halide ion-induced disproportionation of cobalt carbonyls; formation of [Co(CO)4]– and subsequent cyclic ketone synthesis

Paul S. Braterman,   Brian S. Walker  and  Thomas H. Robertson  

Abstract

Free or complexed halide ions catalyse the disproportionation of [Co2(CO)8] and [Co4(CO)12] to give [Co(CO)4]–(I) in ethers or, using [K(crown)]2[CoX4](crown = dicyclohexyl-18-crown-6), in benzene; (I) reacts with o-xylylene dihalides (IIa,b), 2,3-bis(bromomethyl)naphthalene (III), or sebacoyl chloride to give indan-2-one (IV), 1H-benz[f]inden-2-(3H)-one (V), or [(OC)4CoCO[CH2]8COCo(CO)4], benzene being the preferred solvent for the latter two reactions.
