✦ Synopsis

Transition-metal ions / Bond activation, CH and CC / Tandem mass spectrometry / Amines, aliphatic

The mechanisms of the deceptively similar gas-phase chemistry of amine complexes RC(CH&CH2NH2/M+ (R = H, CH,; M = Fe, Co, Ni) are uncovered by the use of deuterium-la-beled compounds. It is demonstrated that the details of CH/ CC bond-activation reactions are strongly metal-ion-dependent, as is the product distribution itself.

Rccent studies of transition-metal ion complexes of aliphatic amines did not only require a revision and modification') of the traditional concept" for the activation of CH/CC bonds in organometallic systems in the gas phase3), but evidence could also be provided4' that direct activation of a CC bond by bare metal ions
