Transition metal alkane complexes

Article Abstract:

The coordination of alkane with d(super 6) metal carbonyl complex, activation followed by a cleavage of carbon-hydrogen bond or the direct complexation of alkanes with metal ions in gas phase give transition metal alkane complexes. Bulky phosphine ligands enhance the stability of transition metal alkane complexes, though they are unable to avoid agostic interactions. A correct orientation of the ligand shell traps an alkane for binding to the metal center to give a stabilized complex. The further incorporation of a transition metal ion activates the trapped alkane.

Transition metals in atmospheric liquid phases: Sources, reactivity, and sensitive parameters

Article Abstract:

An overview of the transition metal ion (TMI) chemistry in the atmosphere and the main uncertainties that still exist as to the physical and chemical processes involved is presented. The source of TMI in atmospheric liquid phases is presented and the way they are transferred is described.
