Reactions of aziridine and oxirane with manganese and rhenium carbonyl complexes. Syntheses of neutral 5-membered cyclic aminooxy- and dioxycarbene compounds

In the presence of a halide ion catalyst, aziridine (HNCH2CH2) and oxirane (OCH2CH2) react with one CO group in M(CO)5X (M = Mn, Re) to form the corresponding cyclic aminooxy- and dioxycarbene compounds according to M(CO)5X + YCH2CH2 →25°CBr- Cis-M(CO)4X(COCH2CH2Y) where M = Mn, X = Br and I, Y = NH; M = Mn, X = Cl, Br, and I, Y = O; and M = Re, X = Cl, Br, and I, Y = NH and O. Even in the absence of any added Br-, M(CO)5Br reacts with excess HNCH2CH2 in CH3CN to form the corresponding aminooxycarbene derivatives. On the basis of spectral data, these compounds have been assigned a cis structure. One bis(dioxycarbene) compound, fac-Re(CO)3Cl(COCH2CH2O)2 has also been isolated from the products of the reaction of Re(CO)5Cl with oxirane. The action of aziridine on Mn(CO)5Cl in the absence of Br- yields a substituted product Mn(CO)3Cl(HNCH2CH2)2. The IR and 1H and 13C NMR spectra of the complexes and also general trends in reactivities of YCH2CH2 with metal carbonyl complexes are discussed.
