2012 m. Nr. 1 Synthesis of novel 2,4,6-triarylpyrimidines
A series of new 2,4,6-triarylpyrimidines bearing π-conjugated aryl units in positions 4 and 6 of the pyrimidine ring were synthesized by palladium-catalyzed cross-coupling reaction of 2-(4-ethylphenyl)- and 2-(4-dimethylaminophenyl)-4,6-dichloropyrimidines with arylboronic acids in the presence of Pd(PPh3)2Cl2 / K3PO4 as a catalyst system. The structure of the synthesized compounds was established by spectral and elemental analysis data. The synthesized 2,4,6-triarylpyrimidines were found to exibit UV-blue fluorescence.
