5-Substituted-benzoxathiol-2-ones

摘要

Novel, biologically active, 5-substituted-1,3-benzoxathiol-2-ones are prepared by the reaction of 5-hydroxy-1,3-benzoxathiol-2-one with a substituted isocyanate in the presence of an activating agent and an appropriate organic solvent. The novel compounds are suitable for use as fungicides and as the active constituents in fungicidal compositions.
