Abstract
The reaction of cationic complex [(5-C5Me5)Re(CO)3I]+ with aliphatic and aromatic primary amines unexpectedly produced the chelated carbamoyl species trans-(5:1-C5Me4CH2NRC({double bond, long}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, 1H and 13C NMR spectroscopies, mass spectrometry and elemental analysis. © 2009 Elsevier B.V. All rights reserved.
