A synthesis method which comprises reacting NH group-containing compounds with thiocyanates, cyanamides, nitriles 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.
一种合成方法,包括在硅烷化剂存在下使含 NH 基团的化合物与硫氰酸盐、氰胺、腈或酯反应,以合成相应的含氮加成或取代产物。 这种方法不仅能直接有效地合成含氮化合物,包括异硫脲类、胍类、脒类和酰胺类,而且应用广泛,适合大规模合成。
