Twenty-one derivatives of imidazolidine-2,4-dione have been prepared by reactions of substituted amino acids with aryl isocyanates in aqueous medium.Pre- and post-emergent herbicidal activities of all the compounds have been tested, and stability of five derivatives has been followed in aqueous medium within the pH range from 7.6 to 13.0.The highest pre-emergent herbicidal activity has been found with the derivatives XI-XVI which inhibit the growth of most indicator plants at the doses of 1.6 kg/ha.The derivatives studied are relatively stable in aqueous medium, the hydrolysis half-life of the compound XI being 9 days at pH 8.

The unimolecular reaction of seven 3-arylhydantoins, relatively slow fragmentation in the free drift region, has been investigated by analysis of the mass-analysed ion kinetic energy (m.i.k.e.) spectrum using direct analysis of daughter ions (d.a.d.i.).Ar
