Шаблон:Chembox (Benzylideneacetone)iron tricarbonyl is the organoiron compound with the formula (CШаблон:SubHШаблон:SubCH=CHC(O)CHШаблон:Sub)Fe(CO)Шаблон:Sub. It is a reagent for transferring the Fe(CO)Шаблон:Sub unit.[1] This red-colored compound is commonly abbreviated (bda)Fe(CO)Шаблон:Sub.
Structure and bonding
(bda)Fe(CO)Шаблон:Sub is an example of a [[Transition metal complexes of aldehydes and ketones|complex of an ηШаблон:Sup-ketone]]. It is a piano stool complex. The compound is characterized by IR bands at 2065, 2005, and 1985 [[wavenumber|cmШаблон:Sup]] (cyclohexane solution), the three bands being indicative of the low symmetry of the complex, which is chiral.
It is prepared by the reaction of [[diiron nonacarbonyl|FeШаблон:Sub(CO)Шаблон:Sub]] with benzylideneacetone.[2]
(bda)Fe(CO)Шаблон:Sub sometimes reacts with Lewis bases to give adducts without displacement of the bda.[3] The reagents of the type (bda)Fe(CO)Шаблон:Sub(PRШаблон:Sub) function as sources of "Fe(CO)Шаблон:Sub(PRШаблон:Sub)" (R = aryl, etc.).[4]
Other sources of Fe(CO)Шаблон:Sub are FeШаблон:Sub(CO)Шаблон:Sub and Fe(CO)Шаблон:Sub(cyclooctene)Шаблон:Sub. The latter is highly reactive and thermally sensitive. Imine derivatives of cinnamaldehyde, e.g. CШаблон:SubHШаблон:SubCH=CHC(H)=NCШаблон:SubHШаблон:Sub, also form reactive Fe(CO)Шаблон:Sub adducts, which have been shown to be superior in some ways to (bda)Fe(CO)Шаблон:Sub.[5]
