New substituted derivatives of 1,2,6-triphenyl-4(1H)-pyridone are now provided, which are useful as fungicidal agent having practically valuable and improved fungicidal activities against a variety of phyto-pathogenic microorganisms, especially fungi and which show low toxicity to animals, including humans. These new compounds may be produced by different processes.

1,2,6-Triphenyl-4(1H)-pyridinone derivatives, and their use as fungicides

As new compounds are provided 2-(4',6'-di-substituted pyrimidine-2'-yl)oxy- or thio-benzoic acid derivatives of the formula ##STR1## wherein R is hydrogen, hydroxy, alkoxy, alkenyloxy, alkylthio or other substituents, R.sup.1 and R.sup.2 are each a halo, alkyl, alkoxy or other substituents; and X is oxygen or sulfur atom. These new compounds are useful as herbicidal agent effective to inhibit the growth of annual weeds and also perennial weeds predominant in irrigated fields of aquatic rice plants and in plowed fields.

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.
