The preparation, characterization and carbonylation products of the ring-functionalized alkyl zirconocenes, (η5C5H5)(η5-C5H4-P(C6H5)2Zr(CH2C6H5)2 (1), (η5-C5H4-P(C6H5)2)2Zr(CH2C6H5)2 (2) are described. These compounds insert one molecule of CO to give products which interconvert between an acyl form and a phosphonium-alkoxide form at ambient temperatures via a reversible nucleophilic attack of the
