应用
1-(3,5-bis(trifluoromethyl)phenyl)-3-(2-(difluoroboryl)phenyl)urea is a robust and user-friendly white solid capable of being stored on the benchtop indefinitely. The strategic incoporation of the difluoroboryl substituent renders this the most acidic urea catalyst reported to date (pKa(DMSO) = 7.5). This difluorboronate urea benefits from enhanced reaction rates and yields when compared to traditional urea catalysts. It also enables reactions that are inaccessible with conventional urea catalysis.
