(Benzylideneacetone)iron tricarbonyl
The organometallic compound (benzylideneacetone)iron tricarbonyl is a widely employed reagent for transferring the Fe(CO)3 unit to other organic molecules.[1] 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 ethoxyethane.[2] The identity and purity of the compound can be determined by its IR spectrum: it absorbs strongly at 2065, 2005, 1985 cm−1, in cyclohexane solution. Additional recommended knowledgeRelated Fe(CO)3 transfer agentsA popular source of Fe(CO)3 is the simplest, 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.[3] (bda)Fe(CO)3 reacts with Lewis bases to give adducts without displacement of the bda.[4] References
