Description

The reaction conditions of 6-methyl- and 6-phenyl-2-thiouracil with halogenoalkanes, activated by nitrile groups, are investigated; as result, preparation of 2-alkyliden-1,3-dihydropyrimidine-4-ones is worked out. It is set that the absorption spectrums of pyrimidines derivatives solutions are characterized by wide bands in UV, that correspond ?-?*- transition (?max=214-362 nm, lg?=4,0-4,7). There is bathochromic shift of absorption bands on 30-60 nm and increase of absorption intensity in two times at introduction of aromatic substituents. Compounds are also characterized by the wide fluorescence bands at 380-550 nm and quantum yields are 0,0295-0,0862. It is also characteristically for the phosphorescence that is observed in area of 420-680 nm. Intensive luminescent signal is observed in lanthanides complexes with 2-alkylidenepyrimidines containing in position "2" acetyl, ethoxycarbonyl, and nitrile groups. For such complexes luminescence is fixed in visible (Eu (III) and Tb (III)) and near IR (Yb (III)) areas
