Scalable Synthetic Strategy for Unsymmetrical Trisubstituted s-Triazines

A scalable synthetic strategy to produce a large variety of unsymmetrical trisubstituted 1,3,5-triazines was developed. This protocol applied in situ formed acyl isocyanate from amide to react with amidine, introducing two substituents to the 1,3,5-triazinone ring with a low production cost and a simple workup procedure. The scalability of this method was demonstrated by translating a small-scale procedure to a multi-kilogram-scale synthesis. Chlorination and a further coupling reaction with various nucleophiles could provide unsymmetrical trisubstituted 1,3,5-triazines bearing diverse functional groups.

Synthetic method for aryl formyl isocyanate

The invention relates to a preparation method, and mainly relates to a synthetic method for aryl formyl isocyanate, which includes: (1) dropwise adding an aryl formamide solution, dissolved in an organic solvent, to a bis(trichloromethyl)carbonate solution; (2) slowly heating the mixture to a high temperature of 60-180 DEG C, and at the temperature, completely dropwise adding the rest of the bis(trichloromethyl)carbonate to the solution in the step (1) within 0.5-5 h, and then continuously performing the reaction for 1-6 h, after the reaction is finished, recycling the organic solvent, and performing pressure-reduced distillation to the organic solvent to prepare the aryl formyl isocyanate. The method overcome the problems of poor safety and high investment cost due to use of oxalyl chloride or carbonyl chloride in the prior art. The method has reasonable processes, is environment-friendly, low-cost, safe and reliable, is high in yield of the aryl formyl isocyanate, is low in generation of waste water, waste gas and solid wastes, and is suitable for industrial production.
