Intramolecular Si−Si Bond Activation by the Iron Carbonyl Unit in an (η4-Silole)tricarbonyliron Complex
摘要:
Intramolecular activation of the Si-Si bond linked to an eta(4)-silole ligand by a metal center was observed when 1,1-bis(trimethylsilyl)tetraphenylsilole was heated with Fe(CO)(5) in refluxing p-xylene, to produce eta(4)-(1-trimethylsilyl-1-methyltetraphenylsilole)Fe(CO)(3) as the final product.

Three different types of silacyclopentadienyl anions have been obtained in the reduction of 1-methylsilole 1 with excess lithium. Treatment of lithiated solution with dimethylchlorosilane gave 2,5-bis(dimethylsilyl)silole derivatives 3a and 3b, and with trimethylchlorosilane gave 1-trimethylsilyl-1-methylsilole derivative 4 at an early stage, and 1,1-bis(trimethylsilyl)silole derivative 8 at a late stage. Silole 1,1-dianion 7 has been formed via silole 2,5-dianion 2 and silole 1-anion 5.
