Disclosed is a method for producing N,N'-carbonyldiazoles by reacting azoles with phosgene in polar solvents from the group comprising ethers, ketones, and chlorinated aliphatic solvents. According to the inventive method, the azole and the phosgene are dosed such that 0.17 to 0.37 mole of phosgene are dosed during the time one mole of azole is dosed.
