摘要：

The electron rich iron complexes (C5Me5)Fe(dppe)Cl (3) and (C5Me5)Fe(dppe)Br (4) do not react with Li(C equivalent toC)(n)SiMe3 (n = 1, 2). Treatment of the chloro iron complex 3 with Me3SiC equivalent toC-C equivalent to CSiMe3 in methanol and in the presence of NaBPh4 provides the binuclear complex (C5Me5)(dppe)FeC equivalent toC-C equivalent toC-Fe(dppe) (C5Me5) (10) as the unique product of this clean reaction (73%). Reaction of the chloro iron derivative 3 with one equivalent of trimethylsilyl(1,3-butadiyne) in triethylamine as a solvent and in the presence of NaBPh4 yields 82% of the mononuclear iron trimethylsilyl-l,3-butadiyne compound. The triethylamine acts as a base to selectively deprotonate the putative butatrienylidene intermediate. (C) 2001 Elsevier Science B.V. All rights reserved.
