Palladium-catalyzed amidation of 2-chloropyrimidines
A mild and efficient Pd-catalyzed coupling of amides with 2-chloropyrimidines is described. The use of bidentate phosphines, such as Xantphos (7), as supporting ligands was found to be crucial for providing high yields of 2-(N-acylamino)pyrimidine couplin

Pyridine-derived heterocycles as potential photoacylating reagents
We prepared several pyridine-derived heterocycles and investigated their photoacylating properties. Among representatives of 4 families of compounds (1-acetyl-7-azaindole, 1-acetyl-7-azaindoline, 2-acetamindpyridine and 2-amidopyrimidines), the 2-aminopyrimidine derivatives were the most promising candidates. Photoacylation of dodecylamine yields up to 47% were obtained, upon irradiation with UV light at 254 nm.
