Direct Transformation from Arylamines to Aryl Naphthalene-1,8-diamino Boronamides: A Metal-Free Sandmeyer-Type Process.

ABSTRACT: A direct metal-free transformation from arylamines to aryl naphthalene-1,8-diamino boronamides, a type of masked boronic acid, has been developed based on Sandmeyer-type reactions. A nonsymmetrical diboron reagent, B(pin)-B(dan), was utilized as the borylating reagent, and the B(dan) moiety was transferred to the aim products selectively. This conversion tolerated a series of functional groups, including chloro, bromo, fluoro, ester, hydroxy, cyano and amide.
