Reactions of acylzirconocene chloride with nucleophiles: bimodal reactivity at β- and acyl carbons of α,β-unsaturated acylzirconocene chloride

Reactions of α,β-unsaturated acylzirconocene chloride with nucleophiles showed novel bimodal reactivity at the β- and acyl carbons depending upon the nucleophile employed, and the formation of ketone α,β-dianionic species was also observed.
