Notizen: The mechanisms of the deceptively similar gas-phase chemistry of amine complexes RC(CH3)2CH2NH2/M+ (R = H, CH3 M = Fe, Co, Ni) are uncovered by the use of deuterium-labeled compounds. It is demonstrated that the details of CH/CC bond-activation reactions are strongly metal-ion-dependent, as is the product distribution itself.

Thema: Chemie und Pharmazie

Notizen: By screening the reactions of alkyl isocyanides RNC with most of the d-block transition metal ions several trends are uncovered that permit a deeper insight in the intrinsic properties of the metal ions. The ability of C - H activation, relative binding energies to alkenes and hydrogen isocyanide as well reactivity in general can be deduced from collisional activation of RNC/M+ complexes, using tandem mass spectrometry methodologies.
