NH-Acidities of Some Sterically Hindered Ureas†

Abstract

Introduction of an N-methyl group in to ethyl N-methylhydantoate causes a fourfold decrease in the rate of base-catalysed exchange of the N-H proton; a second methyl group restores the rate to close to that of the N-unsubstituted hydantoate; the latter effect is observed for N-phenylhydantoates.
