Triazolo(1,5-a)pyridine reacts with aryl halides in presence of catalytic amounts of Pd(OAc) 2 and PPh 3 in DMF to give, in medium or low yield, direct arylations in C3 and pyridyl aryl ketones. Thiazole and benzothiazole have been directly arylated using 7-halotriazolopyridines. These behaviours are unprecedented in the chemistry of (1,2,3)triazolo(1,5-a)pyridines.
