    摘要: Method of controlling fungal diseases in plants and Compositions effective therefor are shown. The method comprises the steps of applying an effective amount of a substituted derivative of 1,1,-dichloroalkene-1 of the general formulaR--X--(CH.sub.2).sub.n --CH.dbd.CCl.sub.2In this generalized formula R is an alkyl group having 1 to 12 carbon atoms, a phenyl group, a di-chloro-phenyl group, a methyl-phenyl group, a nitro-phenyl group, a benzyl group, a chloro-benzyl group, a di-chloro-benzyl group, a methyl-benzyl group, a phenethyl group or a benzothiazolyl group; X is sulfur, a sulfinyl group or a sulfonyl group; and n is an integer of 3,5, and 7.

    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.
