In this study, N,N,N′,N′-tetrabromobenzene-1,3-disulfonamide and poly(N-bromo-N-ethylbenzene-1,3-disulfonamide) were used as efficient catalysts for the one-pot synthesis of 3,5,6-trisubstituted-1,2,4-triazines from readily available acid hydrazides, ammonium acetate and dicarbonyl compounds at 100 °C in good to excellent yields under solvent-free conditions.
在这项研究中,N,N,N ',N'-四溴苯-1,3-二磺酰胺和聚(N-溴-N-乙基苯-1,3-二磺酰胺)被用作有效的催化剂,一锅法合成了苯胺。 3,5,6-三取代-1,2,4-三嗪来自于100°C易得的酰肼,乙酸铵和二羰基化合物,在无溶剂条件下产率高至优异。
