This article describes four methodologies for the formation of five- membered carbocycles from zirconacycles. (1) Insertion reaction of CO or RNC to zirconacycles; (2) Reaction of zirconacycles with propynoate-combination of double Michael addition; (3) Reation of zirconacycles with iodopropenoates or iodocycloenones-combination of coupling reaction and Mechael addition; (4) Reaction of zirconacycles with acyl chlorides-combination of nucleophilic substitution and nuleophilic addition. Each of them has shown numeral representatives.

Key words: ZIRCONIUM, INDUCTION, FIVE MEMBER RING HETEROCYCLIC COMPOUNDS, REACTION MECHANISM, CARBON MONOXIDE, ADDITION REACTION
