Remarkable reactions of (η4-1-azadiene)Fe(CO)3 complexes with aryllithium reagents. Syntheses and structures of novel chelated furanyl-coordinated alkoxy(amino)carbeneiron, η4-azadiene-coordinated 17e acyliron, and iron inner salt complexes

The reactions of a (η4-1-azadiene)Fe(CO)3 complex [(η4-C4H3OCH=CHCH=NC6 H11)Fe(CO)3] (1), with aryllithium reagents, ArLi (Ar =C6H5, p-CH3C6H4, o-CH3OC6H4, p-CH3OC6H4, p-CF3C6H4), in ether at low temperature followed by alkylation with Et3OBF4 in aqueous solution at 0°C or in CH2Cl2 at -60°C gave novel chelated furanyl-coordinated alkoxy(amino)carbeneiron complexes [{η4-C4H3OCH=CHCH(Ar)N(C6H5 )C(OC2H5)=}Fe(CO)2] (4, Ar = C6H5; 5, Ar = p-CH3C6H4; 6, Ar = o-CH3OC6H4; 7, A p-CH3OC6H4; 8, Ar = p-CF3C6H4). The analogous reactions of compounds [(η4-C4H3OCH=CHCH=NC6 H11)Fe(CO)3] (2) and [(η4-C6 H5CH=CHCH=NC6H11)Fe(CO)3] (3) with ArLi (Ar = C6H5, o-, m-, p-CH3C6 H4) afforded novel η4-azadiene-coordinated 17e acyliron complexes [{η4-C4H3 OCH=CHCH=NC6H11}Fe(CO)2(COAr)] (9, Ar = C6H5; 10, Ar =o-CH3C6H4; 11, Ar =m-CH3C6H4; 12, Ar = p-CH3C6H4) and [(η4-C6H5CH=CHCH=NC6 H11)Fe(CO)2(COAr)] (15, Ar = C6H5; 16, Ar = m-CH3C6H4; 17, Ar = p-CH3C6H4), respectively. Unexpectedly, 2 reacts similarly with p-CH3OC6H4Li and p-CF3C6H4Li to yield novel η2-azadiene-coordinated acyliron inner salt complexes [{η2-C4H3O-CH=CHCH=N(C2 H5)C6H11}Fe(CO)3 (COAr)] (13, Ar = p-CH3OC6H4; 14, Ar = p-CF3C6H4). Analogous acyliron inner salt complex [{η2-C6H5CH=CHCH=N(C2 H5)C6H11}Fe(CO)3 (COC6H4CH3-p)] (18) was also obtained from the reaction of 3 with p-CH3OC6H4Li. However, similar reactions of 3 with ArLi (Ar = o-CH3C6H4, o-CH3OC6H4, p-CF3C6H4) produced η2-azadiene-coordinated aryliron inner salt complexes [{η2-C6H5CH=CHCH=N(C2 H5)C6H11}Fe(CO)3Ar] (19, Ar = o-CH3C6H4; 20, Ar = o-CH3OC6H4; 21, Ar = p-CF3C6H4). The structures of 6, 10, 13, and 18 have been established by X-ray diffraction studies.
