英文摘要	Bis(alkynyl)silanes react with low valent zirconocene species to afford zircon cyclobutene intermediates. These in situ generated reactive organometallic intermediates can react with alkynes, ketones, aldehydes, and isocyanates by means of a novel skeletal rearrangement. When a zirconacy-clobutene intermediate was treated with an alkyne, an alpha-alkynylsilyl zirco-nacyclopentadiene was formed. Addition of dimethyl acetylenedicarboxylate (DMAD) and CuCl resulted in one-pot formation of an alkynylsilyl-benzene derivative from three different alkynes. At a higher temperature, the alpha-alkynyl-silylzirconacyclopentadiene was transformed by means of an intramolecular skeletal rearrangement to a zirconacy-clohexadiene-silacyclobutene fused-ring compound, which reacted with DMAD in the presence of CuCl affording the same alkynylsilyl-benzene derivative. When treated with a ketone, an aldehdye, or an isocyanate, the zirconocyclobutene intermediate also underwent the above-mentioned skeletal rearrangement, generating zirconocene-mediated cross-coupling products.; Chemistry, Multidisciplinary; SCI(E); EI; PubMed; 32; ARTICLE; 6; 1895-1902; 11
