Reactions of rhenium carbonyl halides in an atmosphere of ionized ammonia

1. The ionization of Re(CO)5X in mixture of vapors of Re(CO)5X+ complexes (X=Cl, Br, I) with ammonia proceeds by charge transfer with NH3+ ions at ammonia pressures of ∼0.1 torr. 2. Information was obtained on the mechanism of the ion-molecule reactions of rhenium carbonyl halide ions using a formal kinetic analysis of high-pressure mass spectrometric method. 3. The formation of ammonia-containing ions proceeds by substitution of the CO groups of the carbonyl-containing rhenium ions by an ammonia molecule.
