A synthesis method which comprises reacting NH group-containing compounds with thiocyanates, cyanamides, nitrites or esters in the presence of a silylating agent to synthesize the corresponding nitrogen-containing addition or substitution products. This method not only enables the direct and efficient synthesis of nitrogen-containing compounds including isothioureas, guanidines, amidines and amides, but it also has a wide range of applications and is suitable for large-scale synthesis.
该合成方法包括在硅基化剂的存在下,将含有NH基团的化合物与硫氰酸盐、氰胺、亚硝酸盐或酯反应,以合成相应的氮化加成或取代产物。该方法不仅能够直接高效地合成包括异硫脲、鸟氨酸、酰胺和酰胺类在内的氮化合物,而且具有广泛的应用范围,适用于大规模合成。
