NEW ORGANIC LIGANDS OF THE TERPYRIDINE SERIES:MODIFICATION OF GOLD NANOPARTICLES, PREPARATION OF COORDINATION COMPOUNDS WITH Cu(I), CATALYSIS OF OXIDATION REACTIONS

摘要

Organic ligands containing terpyridine and disulfide groupings linked between one another by a bonding –O(CH_2)_n- (n = 6, 12) fragment have been synthesized. Gold nanoparticles of mean size 1.8 nm modified with the indicated ligand were obtained by the method of Brust. By methods of electron spectroscopy and cyclic voltamperometry, the possibility of forming of coordinated compounds on the surface of gold nanoparticles modified by a terpyridine ligand, on interaction with Cu(MeCN)4ClO4 has been shown. The obtained nanoparticles catalyze the oxidation of 2,4-di-tert-butylphenol into 3,3',5,5'-tetra(tert-butyl)biphenyl-2,2'-diol.
