The zirconocene complex of 3-methoxy-4-[(methyl)zirconocene]banzyne, 1, has been prepared and isolated as its trimethylphosphine adduct. In addition, the reaction of 1 with a variety of unsaturated organic molecules has been investigated. In these reactions, 1 serves as the synthetic equivalent of the bis(zirconocene)3-mathoxybenzdiyne complex.
