The reaction of cationic complex [((5)-C5Me5)Re(CO)(3)I](+) with aliphatic and aromatic primary amines unexpectedly produced the chelated carbamoyl species trans-((5):(1)-C5Me4CH2NRC(=O))Re(CO)(2)(I) (1, R = Me; 2, R = Pr; 3, R = Ph; 4, R = p-tolyl). The (1)-coordination of carbamoyl moiety linkages to a methylene group of tetramethylcyclopentadienyl ligand was confirmed by X-ray crystallography of complex 3. All the complexes were isolated as pure samples and fully characterized by IR, H-1 and C-13 NMR spectroscopies, mass spectrometry and elemental analysis. (C) 2009 Elsevier B.V. All rights reserved.
