✦ Synopsis

Reactions of organo-metal compounds O 0350 CO Insertion Reaction of Zirconacyclopentadienes. -Alkyl-substituted zirconacyclopentadienes react with CO directly at room temperature to give cyclopentenone derivatives as mixtures of trans/cis isomers after hydrolysis. Cyclopentadienones are not formed. If zirconaindene (V) is treated under these conditions, both indanones and indenones are obtained. A mixture of double bond isomers is derived from unsymmetrical zirconacyclopentadiene (IX). -(XI*, Z.
