Platinum catalyzed diboration using a commercially available catalyst:: Diboration of aldimines to α-aminoboronate esters

[GRAPHICS] Commercially available Pt(cod)Cl-2 catalyzes the diboration of alkenes, alkynes, and aldimines using bis(catecholato)diboron (cod = 1,5-cyclooctadiene). Catalyzed aldimine diboration provides the first direct route to alpha-aminoboronate esters. The diboration product from N-benzylidene-2,6-dimethylanilline is structurally characterized.
