2-Trimethylsilyl-1-oxa-1,3-butadiene (7) reacts with Fe2(CO)9 to form an unstable tetracarbonyliron (0) complex (8) whereas 2-trimethylsilyl-4-phenyl-1-oxa- 1-oxa-1,3-butadiene (9) and 2-(tert-butyldimethylsilyl)-4-phenyl-1-oxa-1,3-butadiene (20) react with Fe2(CO)9 to form highly stable crystalline tricarbonyliron(0) complexes (16 and (21). Complexes (16) and (21) both undergo acylation when reacted with methyl lithium under nitrogen to form γ-ketoacylsilanes [(18) and (22)], but only complex (21) reacts with methyl lithium under carbon monoxide to give the tricarbonyl(vinylketene)iron(0) complex (23).
