Abstract

Several 4′-aryl-substituted 2, 2′: 6′, 2 ″-terpyridines (tpy-C 6 H 4 R) have been prepared by palladium-catalysed cross-coupling of 4′-bromoterpyridine or 4′-triflate- terpyridine (triflate= trifluoromethylsulfonyloxy) with aryl boronic acids or esters, RC 6 H 4 B (OR′) 2 (R= H, m-NH 2, p-CHO,-NO 2,-CN,-NMe 2,-NPh 2). The new ligand 4′- mesitylterpyridine (mesityl= 2, 4, 6-trimethylphenyl) was prepared in the same way. ...
