(Equation presented) Commercially available α-aminodiphenylmethane 1 (benzhydrylamine) serves as a convenient ammonia equivalent in the dimethyltitanocene-catalyzed intermolecular hydroamination of alkynes. The primary formed imines can be hydrogenated and cleaved directly to the corresponding primary amines by catalytic hydrogenation using Pd/C as catalyst.

A simple synthesis of 1-aminoalkanephosphonic acids is described.The addition of diethylphosphite to alkylidene- and arylidenebenzhydrylamines yields the N-benzhydryl-1-aminoalkanephosphonic acid esters.The title compounds are formed by treatment of the N-blocked esters with hydrobromic acid.The starting amine can be recycled from the hydrylbromide. - Key words: 1-Aminoalkane Phosphonic Acids, Benzhydrylic, Schiff Bases
