Abstract:2-(Methylamino)pyridine reacts with RuCl2(CO)3 to give a carbamoyl complex, [Ru(C(O)N(CH3)(C5H4N)Cl(CO)2], which yields with pyridine (py) and acetylacetone (Hacac), respectively, [Ru(C(O)N(CH3)C5H4N)Cl(CO)2(py)] and [Ru(C(O)N(CH3)C5H4N)(CO)2(acac)]. These complexes are characterized spectroscopically. The amino group of the ligand is carbonylated and the resulted carbamoyl ligand is chelating through a pyridine ring-N and a carbamoyl-C atom. 2-Aminopyridine and 2-aminopyrimidine react similarly with RuCl2(CO)3 to give the corresponding carbamoyl complexes.
