Provided is a process for preparing carbonylated derivatives of amino- and haloamino-1,3,5-triazines by contacting the 1,3,5-triazine, carbon monoxide and a metal catalyst system containing a metal promoter for promoting carbonylation, at a temperature, carbon monoxide pressure, and length of time sufficient to carbonylate at least a portion of the amino and/or haloamino groups of the 1,3,5-triazine. The product resulting from contacting these components is an isocyanate functional 1,3,5-triazine; however, the carbamate functional derivative can be readily produced by contacting these components in the further presence of a hydroxy compound, or by post-reacting the isocyanate functional product with such hydroxy compound.
本发明提供了一种制备氨基和卤氨基-1,3,5-三嗪的羰基化衍生物的工艺,其方法是将 1,3,5-三嗪、一氧化碳和含有促进羰基化的金属促进剂的金属催化剂体系,在足以使 1,3,5-三嗪的氨基和/或卤氨基的至少一部分发生羰基化的温度、一氧化碳压力和时间下进行接触。这些组分接触后得到的产物是异氰酸酯官能团的 1,3,5-三嗪;然而,通过在羟基化合物进一步存在的情况下与这些组分接触,或通过异氰酸酯官能团产物与此类羟基化合物的后反应,可以很容易地生产出氨基甲酸酯官能团衍生物。
