  Mechanisms of dicarboximide ring opening in aqueous media: Procymidone, vinclozolin and chlozolinate

  摘要：

  AbstractThe hydrolysis kinetics of the dicarboximide fungicides procymidone, vinclozolin and chlozolinate in neutral and alkaline solutions of pH 60 to 13·7 at 25°C have been determined conjointly by ultraviolet spectrophotometry and by high performance liquid chromatography. Under alkaline conditions, the fungicides undergo attack by the hydroxide ion on a specific carbonyl group and the rate of hydrolysis increases proportionally to the hydroxide ion concentration. Procymidone gives quantitatively and irreversibly 2‐(3,5‐dichlorophenylcarba‐moyl)‐l,2‐dimethylcyclopropanecarboxylate. The reaction is not subject to general base catalysis and experimental data are in agreement with a rate‐determining attack by the hydroxide ion. After a rapid hydrolytic loss of the ethoxycarbonyl substituent from chlozolinate, the dicarboximide ring cleavage of the two other fungicides leads, by mechanisms which differ with respect to the type of base catalysis and the rate‐determining step, to the corresponding anilides, producing as intermediates the carbamic acids, which undergo loss of carbon dioxide. The hydrolysis of vinclozolin and chlozolinate yields, respectively, N‐(3,5‐dichloro‐phenyt)‐2‐hydroxy‐2‐methylbut‐3‐enanilide and N‐(3,5‐dichlorophenyl)‐2‐hydroxy‐propanilide.

  3-Phenyl-oxazolidine-2,4-dione derivatives can be halogenated directly, without splitting of the heterocyclic ring. The products thus obtained have a fungicidal action which is substantially wider than that of compounds hitherto known.

• Kinetics and mechanisms of hydrolysis of dicarboximide fungicides in micellar media

  The kinetics of alkaline hydrolysis of the dicarboximide fungicides procymidone, iprodione, vinclozolin, and chlozolinate (1-4, respectively) were investigated in micellar solutions containing various amounts of either sodium dodecyl sulfate (SDS), cetyltrimethylammonium bromide (CTAB), or three nonionic surfactants (two C-13 alcohols and a copra amine combined with ethoxyl chains) and compared with the kinetics in aqueous media. For all compounds, the rate constants observed are slightly reduced by the SDS micellar media, showing that reactions essentially take place in the aqueous pseudophase. The CTAB micellar media speed up the hydrolysis rates with small quantities of Br- ions in the medium. As the number of Br- ions increases, the rate of reactions falls. This is characteristic of an ion exchange (OH- and Br-) at the surface of the CTAB micelles. Finally, the presence of nonionic micelles has little influence on the hydrolysis of the fungicides: the reduction in the rate of dicarboximide ring opening is attributed to micelle-substrate association. These results can be explained by means of the pseudophase kinetic model coupled with the mechanisms of hydrolysis of these fungicides in water solution.
