  1-Silabicyclo[4.4.0]dec-5-en-4-ones, a novel type of organosilicon compound, have been prepared from 2-methylidene-1-(3-oxopropyl)-1-silacyclohexanes by an ene reaction as the key transformation. Various routes to the starting aldehydes from 3-halopropyl, allyl, or 3-(4-methoxybenzyloxy)propylsilanes have been investigated. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)

• The Scope and Limitations of Intramolecular Radical Cyclizations of Acylsilanes with Alkyl, Aryl, and Vinyl Radicals

  5-Exo cyclizations of primary and secondary radicals with acylsilanes successfully give cyclopentyl silyl ethers. The corresponding 6-exo cyclizations are sensitive to changes of the size of silyl groups. Secondary radicals undergo 6-exo cyclizations with acylsilanes more slowly. Reaction of aryl radical with acylsilane proceeds well for 5-exo cyclization but not for 6-exo cyclization. Vinyl radicals give best results in 5-exo cyclizations with acylsilanes but give low yields (similar to 30%) in 6-exo cyclizations. Intramolecular cyclizations of vinyl radicals with acylsilanes give enol silyl ethers regiospecifically.
• Synthesis of 2-methylidene-1-silacyclohexanes from 2,6-dibromohex-1-ene and polyhalosilanes
  作者：Silvia Díez-González、Luis Blanco

  DOI：10.1016/j.jorganchem.2006.08.061

  日期：2006.12

  Various 2-methylidene-l-silacyclohexanes were prepared by straightforward syntheses from readily available polychloro- or polyfluorosilanes, magnesium and 2,6-dibromohex-l-ene using Barbier-type conditions or a previously synthesized Grignard reagent. Good yields were obtained considering the low stability of the products in the reaction conditions. (c) 2006 Elsevier B.V. All rights reserved.
