“…Amines have applications in many interface related areas including corrosion inhibition, − adhesion, − and heterogeneous catalysis. , In the latter case, amines are commonly used not only as reactants but also as catalyst modifiers. − Pfaltz, for example, has shown that a basic nitrogen group is a necessary component of chiral modifiers for the hydrogenation of α-functionalized ketones. − The interaction of the amine functionality with the surface is therefore a subject of some importance in surface science. Our own interest in amine surface chemistry stems from studies of ammonia oxidation − and of the interaction of pyridine with surface oxygen, where intermolecular complexes between pyridine and both molecular oxygen transients and chemisorbed atomic oxygen , have been demonstrated.…”
