Composite Materials with Improved Properties in Compression: Synthesis of 3-Methylene-1,1-Dichlorosilacyclobutane and 1,1-Dichlorosilacyclopent-3-ene

摘要

Silacyclobutanes have played an important role in the development of modernsilicon chemistry. For example, silacyclobutanes serve as precursors to carbon-silicon double bonded intermediates silenes as well as to pentacoordinate silicon anions in the gas phase. Silacyclobutanes also undergo facile ring opening polymerization. Despite the importance of this ring system surprisingly few functionalized silacyclobutanes and silacyclobutenes have been prepared. Keywords: Dichlorosilacyclopent-3-ene, Dichlorosila cyclobutane, Synthesis, Reactive silicon heterocycles. (JES)
