EXPEDIENT N-ARYLATION FOR THE SYNTHESIS OF 2-ARYLAMINO-3-CYANOPYRIDINES USING IONIC COPPER(I) COMPLEX AS A CATALYST

[摘要]：The N-arylation of 2-amino-3-cyanopyridines is firstly described by using ionic copper(I) complex (Phen)(2)Cu+BF4- (phen = 1,10-phenanthroline) as an efficient catalyst. The synthetic protocol can be applied to synthesize a wide range of 2-arylamino-3-cyanopyridine products in good to excellent isolated yields. The resulted products are potentially building blocks for further preparation of biologically interesting products or useful ligands for metal catalysis.
