The preparation, characterization and carbonylation products of the ring-functionalized alkyl zirconocenes, (η5C5H5)(η5-C5H4-P(C6H5)2)Zr(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 phosphine at the carbenium-like η2-acyl carbon as shown through variable-temperature 1H and 31P{1H} NMR studies.
