|Section2= |Section7= }} The organometallic compound (benzylideneacetone)iron tricarbonyl is a reagent for transferring the Fe(CO)3 unit to other organic molecules.〔Knölker, H.-J. "(η4-Benzylideneacetone)tricarbonyliron" in Encyclopedia of Reagents for Organic Synthesis (Ed: L. Paquette) 2004, J. Wiley & Sons, New York. .〕 This red-colored compound is commonly abbreviated (bda)Fe(CO)3. It is prepared by the reaction of Fe2(CO)9 with benzylideneacetone, typically in refluxing diethyl ether.〔Alcock, N. W.; Richards, C. J.; Thomas, S. E. ”Preparation of Tricarbonyl(η4-vinylketene)iron(0) Complexes from Tricarbonyl(ε4-vinyl ketone)iron(0) Complexes and Their Subsequent Conversion to Tricarbonyl(ε4-vinylketenimine)iron(0) Complexes” ''Organometallics'' 1991, volume 10, pp 231 - 238..〕 The compound is characterized by IR bands at 2065, 2005, and 1985 cm−1 (cyclohexane solution). ==Related Fe(CO)3 transfer agents== A popular source of Fe(CO)3 is Fe2(CO)9. Alternatively, Fe(CO)3(cyclooctene)2 is highly reactive, the trade-off being that it is thermally sensitive. Imine derivatives of cinnamaldehyde, e.g. C6H5CH=CHC(H)=NC6H5, form conveniently reactive Fe(CO)3 adducts, which have been shown to be superior in some ways to (bda)Fe(CO)3.〔Knölker, H.-J.; Braier, A.; Bröcher, D. J.; Cämmerer, S. Fröhner, W.; Gonser, P.; Hermann, H.; Herzberg, D.; Reddy, K. R.; Rohde, G. “Recent applications of tricarbonyliron-diene complexes to organic synthesis” Pure and Applied Chemistry 2001, Volume 73, pp. 1075–1086. 〕 (bda)Fe(CO)3 reacts with Lewis bases to give adducts without displacement of the bda. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「(Benzylideneacetone)iron tricarbonyl」の詳細全文を読む スポンサード リンク
