The photolytically induced CO substitution reactions of CpMn(CO)3 with N-phenylaziridine and of W(CO)6 with 2,2-dimethylaziridine lead to the N-coordinated aziridine complexes Cp(CO)2Mn{N(Ph)CH2CH2} and (CO)5W{N(H)CH2-CMe2}. Both are stable with respect to thermal alkene elimination. The thermal reaction of Cp(CO)3MoCl with N-hydroxyethylaziridine leads to the metallaheterocyclic compound Cp(CO)2MoNH(CH2CH2OH)CH2CH 2C(O). It might be formed by several reaction steps including a Cl migration with nucleophilic ring opening, a CO insertion reaction forming the β-aminoacyl ligand and finally a hydrolytic process. The X-ray structure analysis of Cp(CO)2Mn{N(Ph)CH2CH2) and (CO)5W{N(H)CH2CMe2) shows three-membered-ring ligands N-bonded to the metal atoms with a trigonal pyramidal configuration at the nitrogen atoms. The X-ray structure analysis of Cp(CO)2MoNH(CH2CH2OH)CH2CH 2C(O) reveals a five-membered heterocyclic ring system, including the molybdenum atom, a carbonyl function and an ammonium center.
