102-07-8 - Uses and synthesis methods
Introduction
1, 3-diphenylurea is a urea compound. Urea refers to a compound containing R1R2N-CO-NR1R2 functional groups, which is the first type of organic compound synthesized artificially.
method of synthesis
1, 3-diphenylurea was synthesized from N-cyclohexanoyloxybenzamide: [RuCl2(p-cymene)]2(0.005),N-cyclohexanoyloxybenzamide (0.2mol), silver acetate (AgOAc)(0.4mol) and dioxane solvent (dioxane)(1mL) were sequentially added to a dry reaction tube at room temperature and under empty atmosphere, then the temperature was raised to 80 ℃ for 12 hours, and the product was separated by column chromatography after the reaction, with a yield of 94%.
Production method
It is obtained by condensation of aniline and urea.
