β-Silyl α,β-unsaturated ketones, R3SiCH=CHC(O)Me (R3Si = Me3Si, ButMe2Si, PhMe2Si), react with at 35 deg C in diethyl ether to give tetracarbonyliron(0) complexes and at 55 deg C in toluene to give tricarbonyliron(0) complexes.Tricarbonyliron(0) and tricarbonyltMe2SiCH=CHC(O)Me>iron(0) react with methyllithium under a nitrogen atmosphere to give hexane-2,5-dione and 3-(tert-butyldimethylsilyl)hexane-2,5-dione, respectively, and with methyllithium under a carbon monoxide atmosphere to give the vinylketene complexes tricarbonyl(3-methyl-5-trimethylsilyl-1-oxa-1,2,4-triene)iron(0) and tricarbonyl(5-tert-butyldimethylsilyl-3-methyl-1-oxapenta-1,2,4-triene)iron(0) respectively.
