英文摘要: Thw reac tions of a (η~4-1-azadiene)Fe(CO)^3 complex, [(η~4-C^4H^3OCH=CHCH=NC^6H^11)Fe-(CO)^3] (1), with aryllithium reagents, ArLi(Ar=C66H^5, p-CH^3C^6H^4, o-CH^30C^6H^4, p-CH^3-OC^6H^4, p-CF^3C^6H^4), in ether at low temperatyure followed by alkylation with Et^3OBF^4 in aqueous sloution at 0℃ or in CH^2Cl^2 at -60℃ gave novel chelated furanyl-coordinated alkoxy(amino)carbeneiron complexes [{η~4-C^4H^3OCH=CHCH(Ar)N(C^6H^5)C(OC^2H^5)=}Fe(CO)^2](4,Ar=C^6H^5; 5, Ar=p-CH^3C^6H^4; 6, Ar=o-CH^3OC^6H^4; 7, Ar,=p-CH^3OC^6H^4; 8, Ar=p-CF^3C^6H^4). The analogous reactions of compounds. [{Ηc^4H^3OCH=CHCH=NC^6H^11)Fe(CO)^3](2)and [{η~4-C^6H^5CH=CHCHNC^6H^11)Fe(CO)^3](3) with ArLi(Ar=C^6H^5,o-,m-,p-CH^3C^6H^4)afforded novel η~4-azadiene-coordinated 17e acyliron complexes[{η~4-C^4H^3PCH=CHCH=NC^6H^11}Fe(CO)^2(CO)^2(COAr)] (9, Ar=C^6H^5; 10, Ar=o-CH^3C^6H^4; 11, Ar=m-CH^3C^6H^4; 12, Ar=p-CH^3C^6H^4) and [{η~4-C^6H^5CH=CHCH=NC^6H^11)Fe(CO)^2(CO)Ar)(15, Ar=C^6H^5; 16, Ar=m-CH^3C^6H^4; 17,Ar=-p-CH^3C^6H^4), respectively. Unexpectedly, 2 reacts similarly with p-CH^3-OC^6H^4Li and p-CF^3C^6H^4Li to yield novel η^~2-azadiene-coordinated acyliron inner salt complexes [{η~2-C^4H^3O-CH=CHCH=N(C^2H^5)C^6H^11}Fe(CO)^3(COAr)](13, Ar=p-CH^3OC^6H^4; 14, Ar=p-CF^3C^6H^4). Analogous acyliron inner salt complex[{η~2-C^6H^5CH=CHCH=N(C^2H^5)-C^6H^11}Fe(CO)^3(COC^6H^4CH^3-p)] (18) was also obtained from the reaction of 3 with p-CH^3-OC^6H^4Li. However, similar reactions of 3 with ArLi (Ar=o-CH^3C^6H^4, o-CH^3OC^6H^4, p-CF^3C^6H^4) produced η~2-azadiene-coordinated aryliron inner salt complexes [{η~2-C^6 H^5CH=CHCH=N(C^2H^5)C^6H^11}Fe(CO)^3Ar](19, Ar=Och^3c^6h^4; 20 Ar=OCH^3OC^6H^4; 21, Ar=p-CF^3C^6H^4).The structures of 6, 10, 13, and 18 have been estab lished by X-ray diffraction studies.
