Formation of a di-iron-µ-vinylidine group from ethylene: synthesis and crystal structure of {MeSi(CH2PMe2)3}Fe(µ-C
CH2)(µ-H)2Fe{(PMe2CH2)3SiMe}
Abstract
Treatment of (η4-C6H6)(tmps)Fe, tmps = MeSi(CH2PMe2)3, with ethylene, or sodium amalgam reduction of (tmps)FeCl2 in the presence of ethylene, gives the di-iron-µ-vinylidene compound (tmps)Fe(µ-CCH2)(µ-H)2Fe(tmps) whose crystal structure has been determined.
