2-Imidazoline (dihydroimidazoles) is one of three isomers of the nitrogen-containing heterocycle with formula C3H6N2, derived from imidazole. The 2-imidazolines are the most common imidazolines commercially, as the ring exists in some natural products and some pharmaceuticals. They also have been examined in the context of organic synthesis, coordination chemistry, and homogeneous catalysis.
