Technical Notes:
1.L igand for iron catalyzed ethene polymerization, activated and heterogenized with a co-catalyst consisting of partially hydrolyzed trimethylaluminum on silica gel
2.L igand for chromium catalyzed of ethylene oligomerization
3.L igand for rhodium bis(imino )pyridine complex, that generates nanoparticles and effectively catalyses dehalogenation and hydrogenation of aromatic Compounds
