N,N′-disubstituted ureas: Influence of substituents on the formation of supramolecular polymers

Symmetrical N,N′-disubstituted ureas have been synthesized and characterized. Among them, the branched dialkylureas prepared are highly soluble in organic media. Moreover, the solutions obtained are very viscous in heptane, if the branched alkyl groups are not too bulky (i.e. a methyl group on the α carbon, or an ethyl group on the β carbon). Due to the strong, bifurcated hydrogen bonds between the urea moieties, linear supramolecular polymers are formed. The degree of association of these supramolecular polymers has been determined by FTIR spectroscopy.

New synthetic strategy for urea herbicides

This work describes an effective and a safe procedure for the preparation of commercially applicable trisubstituted ureas derived from their thio analogues which result from the thiuram disulfides in quantitative yields.

The Application of N-Substituted Trichloroacetamides as in situ Isocyanate Generating Reagents for the Synthesis of Acylureas and Sulfonylureas

In dimethylsulfoxide solution in the presence of excess of powdered sodium hydroxide, N-substituted trichloroacetamides 1 are used as in situ isocyanate generating reagents which can react with carboxamides or sulfonamides 2 to afford acylureas or sulfonylureas 3.
