文摘
Addition of aluminum chloride to the(
4-cyclohexadiene)Fe(CO)3 complexbearing an acidchloride side chain at C-5 gives a cyclic keto complex, whereas Lewisacid assistedintramolecular cyclization of acyclic(4-butadiene)Fe(CO)3 complexescontaining an aldehyde,an ester, or a nitrile functionality produces(
,3-allyl)tricarbonyliron complexes.Treatmentsof the (4-butadiene)Fe(CO)3complexes bearing a chromium carbene moiety in refluxingtoluene lead to formation of furan derivatives by intramolecularaddition of the diene ligandto the chromium carbene carbon center.
