(+) -1- (1-Naphthyl) ethylamine

(+) -1- (1-Naphthyl) ethylamine ((+) -1- (1-NEA) ) acts as a chiral modifier to introduce enantioselectivity in catalytic hydrogenation reactions. The 1-NEA compound facilitates H-D exchange with D2 in solution, establishing an N?D bond. This indicates that 1-NEA enables adsorption and protonation on Pt surfaces through its amine N atom, suggesting the potential of NEA molecules to impart enantioselectivity to Pt hydrogenation catalysts.
