Abstract
Publisher Summary This chapter focuses on organometallic compounds of various amino derivatives of pyridine and its benzannulated forms. The range of ligands includes 2-amino- or 2,6-diaminoderivatives where the amino substituent(s) is/are adjacent to the pyridine nitrogen heteroatom, 3- and 4-aminoderivatives, di- and tri-2-pyridylamines, aminomethyl compounds, carboxamides, and some specific ligands. Only organometallic compounds are considered, those with a metal-carbon bond. Deprotonation of (2,6-di- i -propylphenyl)(6-(2,4,6-tri- i -propylphenyl)pyridin-2-yl)amine and (2,6-di- i -propylphenyl)(6-(2,6-dimethylphenyl)pyridin-2-yl)amine using potassium hydride leads to crystalline organometallic polymers of type R=R 1 = i -Pr, where the aryl substituents also participate in coordination. The chapter highlights that alkylamine substituents often give rise to aminocarbene structures located around the central atom. The cyclometalation, borylation, and silylation of substituents, cyclometalation of the heteroring, and protonation of an amino group are features of some of these representatives. Also, aminomethylpyridine ligands typically coordinate via all the available heteroatoms forming bis- and poly-chelates. However, at times a pyridine moiety or an amino group is not coordinated.
