Zirconacycle has attached much attention owing to its various reactive behaviors. α,α'-Bismethylenyl zirconacyclopentane could be prepared by reductive coupling reaction of two 1,1-disubstituted allenes promoted by low covalent zirconocene species "Cp2Zr (II)". The stereo- and regio-chemistry could be affected obviously by steric and electronic effect of the substituents in the allenes. Two sp2 carbon-metallic bonds in α,α'-bismethylenyl zirconacyclopentane could be quenched by several electrophilic system and afford the novel methodologies for the synthesis of 1,1,6,6-tetrasubstituted 1,5-hexadiene, 2,5-dihalo-1,5-hexadiene and 1,6-dicarbonyl compound with the skeleton of 1,5-hexadiene.

Key words: α,α'-bismethylenyl zirconacyclopentane, 1,5-hexadiene, synthesis, selectivity
