摘要

Abstract The title compounds 3 were prepared in low yields from the carbylamine reaction of amino-1, 3, 5-triazines 1 under phase-transfer conditions. Isocyanotriazine 3a readily reacted with amines in the presence of copper salts to afford triazinylformamidines 4, and also with active methylene compounds in the presence of base to afford addition products 5 and 6, indicating the high electrophilicity of 3. The reactions of isocyanotriazine with ...
