title: The substituent-dependent base-treatment chemistry of (eta5-C5H5)Fe(CO)2SiR2SiR2Cl: formation of 1,2-disila-3-metallacyclobutanes, their ring-opened polymers, migrations and substitutions.
abstract: We report the formation of disilametallacycles, high molecular weight polymers or simple substitution products from the reactions of 1-(cyclopentadienyliron dicarbonyl)-2-chlorodisilanes with bases, LDA or n-BuLi.
