  Synthesis and reactivity of iron carbonyl complexes of α,β-unsaturated acyl silanes

  摘要：

  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-1,3-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 gamma-ketoacylsilanes [(18) and (22)], but only complex (21) reacts with methyl lithium under carbon monoxide to give the tricarbonyl(vinylketene)iron(0) complex (23).

  Reductive cleavage of carbon–sulfur linkages of silyl enol ethers of thiocarboxylic S-esters can be induced by treatment with sodium or potassium–sodium alloy in the presence of chlorotrimethylsilane, and the corresponding silyl enol ethers of acyltrimethylsilanes can be prepared in high yields.
