1,6-Diaryl-4-methyl-2[1H]-pyrimidineselenones and 1,4-diaryl-6-methyl-2[1H]-pyrimidineselenones were synthesised by treatment of appropriate pyrimidinethiones with gaseous H2Se. 2D NMR spectroscopic studies were conducted to obtain conformation

1,4,6-Trisubstituted 2(1H)-pyrimidinones (2a-j) are easily converted into the corresponding thiones (3a-j) in high yields by reacting with 2,4-bis(p-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-disulfide (1).Further, other diazines, e.g., 2-methyl-6-phe
Novel Synthesis of Di-imines by the Transformation of 1-Aryl-4,6-disubstituted Pyrimidin-2(1H)-ones

The di-imines (4), which are versatile starting materials for the synthesis of heterocycles, are obtained in fair yields when the 1-aryl-4,6-disubstituted pyrimidin-2(1H)-ones (3) are treated with alkoxide, both photochemically and thermally.The di-imines (4) thus obtained, when treated with disulphide, give the 1,3-thiazine-2-thiones (8) and/or the 1-arylpyrimidine-2(1H)-thiones (9).
