Reactions with polyfunctional ligands

Di- and polydentate ligands (di- and polyfunctional donors) have several reaction centers, and the reaction on any of them is complicated by the competition with other atoms and/or groups, which are potentially capable of interacting with a metal. 

We are investigating a series of reactions of aminopyridines and aminopyrimidines and main group compounds. These heterocycles can form adducts with both kinds of nitrogen atoms pyridinic or anilinic. Bonding of several aminopyridines to heteroatoms such as boron, silicon, or phosphorus gives polyfunctional molecules rich in lone pairs and therefore candidates to be used as ligands.
