英文摘要In this work, we report the synthesis and molecular structures of two kinds of organozinc metallacycles: dilithio spiro zincacyclopentadienes 3 and dizinca[10]cycles 4. Both complexes 3 and 4 were obtained from the reaction of 1,4-dilithio-1,3-butadienes 1 with ZnX2 (X = Cl, Br) in THF. The molecular structure of 3 was determined by single-crystal X-ray structural analysis and shows a spiro ring skeleton in which two zincacyclopentadienes are fused by a Zn(II) atom. Complex 3 represents the first well-defined examples of groups 12 metallacyclopentadienes. The molecular structure of 4 contains a distorted ten-membered dizincacycle. Multinuclear NMR measurements of 3 and 4 were conducted, and the structural transformations between them were observed. In addition, the insertion reaction of these organozinc metallacycles with S-8 or Se were investigated to give their corresponding thiophene or selenophene compounds.
