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 carbon disulphide, give the 1,3-thiazine-2-thiones (8) and/or the 1-arylpyrimidine-2(1H)-thiones (9).
当将1-芳基-4,6-二取代的嘧啶2-2(1 H)-酮(3)处理后,二价亚胺(4)是合成杂环的通用起始原料,并以合理的收率获得。光化学和热的醇盐。如此获得的二亚胺(4),当用二硫化碳处理时,得到1,3-噻嗪-2-硫酮(8)和/或1-芳基嘧啶-2(1H)-硫酮(9)。
