Abstract

Abstract : One Cu(i ) and two Cd(ii ) coordination polymers have been achieved using a 4-mercaptopyridine-functionalized resorcin[4]arene. 1 exhibits predominant efficiency and excellent recyclability for the synthesis of 1, 2, 3-triazoles and β-OH-1, 2, 3-triazoles. Abstract : Three distinctive coordination polymers [Cu2 L2 ]·0.5CH3 OH·1.5H2 O·2CN (1 ), [CdCl2 L]·5DMF·2CH3 OH·2H2 O (2 ) and [Cd2 L(bdc)2 (DMF)]·2DMF·3CH3 OH·H2 O (3 ) were solvothermally synthesized using a resorcin[4]arene ligand (H2 bdc = p -phthalic acid and L = tetrakis(4-mercaptopyridine-ylmethyl)resorcin[4]arene). Among them, 1 exhibits a 3D structure, but 2 and 3 are both charming layers. 1 exhibits efficient and selective catalytic performance for azide–alkyne cycloaddition reactions owing to its rich Lewis acid sites. Remarkably, as a heterogeneous catalyst, 1 could be recycled with preservation of the catalytic capability and structural integrity.
