Ni-Pyridine Complex Formations Investigated in Micro Reactors

3 Ni-Pyridine Complex Formations Investigated in Micro Reactors Organic synthesis 95 [OS 95] Complex formation from Ni ions and pyridine-2-azo-p-dimethylaniline 

The changes in absorption spectra due to the complex formation are given in [17]. 

Depending on what species port was activated , i.e. which reactant stream was moved, different flow modes were available, deliberately changing the concentration profiles in a predetermined manner [17]. These flow modes were termed flow mode , inject mode and restarted flow mode , corresponding to Ni ion channel filling, ligand slug injection and Ni ion movement after slug insertion, respectively. 

At the Ni ion solution/ligand slug interface, the complex is formed, as evidenced by the color change [17]. Since the formation is reversible, decomposition of the complex can also be observed, on reducing the content of pyridine-2-azo-p-dimethylaniline.
