Our purpose is to carry out the systematic studies on the effect of ligands on the Fe catalyzed ATRP reactions. We report some interesting results from the systemic study of 16 ligands. Based on the understanding of the ligands’ effect, we have developed a novel catalyst system of Fe complexes using a combination of ligands. The effect of the donors atoms and the steric influence of ligands on Fe catalyzed ATRP reaction was clarified in the view of the activity, solubility and stability of the Fe catalysts. In the experiment, the researchers used many compounds, for example, 2-Isopropylpyridine (cas: 644-98-4Quality Control of 2-Isopropylpyridine).
2-Isopropylpyridine (cas: 644-98-4) belongs to pyridine derivatives. Pyridine is diamagnetic and has a diamagnetic susceptibility of −48.7 × 10−6 cm3·mol−1.The molecular electric dipole moment is 2.2 debyes. The standard enthalpy of formation is 100.2 kJ·mol−1 in the liquid phase and 140.4 kJ·mol−1 in the gas phase. Halopyridines are particularly attractive synthetic building blocks in a variety of cross-coupling methods, including the Suzuki-Miyaura cross-coupling reaction.Quality Control of 2-Isopropylpyridine
