Treatment of FpCH2SiR2Cl [Fp = (eta5-C5H5)Fe(CO)2] with lithium diisopropylamide leads to the formation of new metallacycle complexes. When R2 = Me2 and MenBu, these ring-open to form a new class of organometallic polymer. When R2 = nBu2, the metallacycle resists ring-opening and may be structurally characterized as the Ph3P-substituted species.
