In 2016,Popowski, Yanay; Goldberg, Israel; Kol, Moshe published 《The stereoselectivity of bipyrrolidine-based sequential polydentate ligands around Ru(II)》.Chemical Communications (Cambridge, United Kingdom) published the findings.Product Details of 31106-82-8 The information in the text is summarized as follows:
The Ru(II) coordination chem. of the sequential hexadentate, tetradentate and the novel hybrid pentadentate ligands assembled around the chiral bipyrrolidine core and including bipyridyl and pyridyl periphery units is described. The bipyridine group exhibited priority in binding over the bipyrrolidine group, which led to a diastereomer mixture in the case of the hexadentate ligand (R,R)-bis(bipyridinylmethyl)-2,2′-bipyrrolidine (1). Employing only monopyridyl or a combination of monopyridyl (3) and bipyridyl (4) peripheral groups restored the chiral induction ability to the bipyrrolidine core resulting in predetermined chiral-at-metal complexes. In addition to this study using 2-(Bromomethyl)pyridine hydrobromide, there are many other studies that have used 2-(Bromomethyl)pyridine hydrobromide(cas: 31106-82-8Product Details of 31106-82-8) was used in this study.
2-(Bromomethyl)pyridine hydrobromide(cas: 31106-82-8) belongs to pyridine. Pyridine is very deactivated towards electrophilic substitution with respect to benzene. For this reason classical formylation, using methods such as the Gattermann or Vilsmeier reactions, are not generally successful. Product Details of 31106-82-8
