    摘要: Novel thioureidobenzene compounds having the general formula ##EQU1## wherein R and R' are lower alkyl groups and X is oxygen or sulfur atom is prepared by reacting a compound having the general formula ##EQU2## wherein Y is chlorine or bromine, with a compound having the general formula ##EQU3## wherein M is ammonium or an alkali metal. These compounds have high miticidal and fungicidal activity.

    摘要: A process for producing a mono- or di-alkali metal salt or alkaline earth metal salt of L-ascorbic acid-2-sulfate which comprises reacting L-ascorbic acid in which the 5 and 6 positions are protected by a ketone or aldehyde, with dimethyl formamide-sulfur trioxide complex, which is produced by a reaction of dimethyl formamide with chlorosulfonic acid and a dehydrohalogenating agent such as pyridine, triethylamine, dimethyl aniline, which is a tertiary amine so as to produce a sulfate, and neutralizing the product with an alkali metal hydroxide or an alkaline earth metal hydroxide, and removing said protecting aldehyde or ketone at 5- and 6-positions.
