Abstract: It is an object of the present invention to provide a novel and advantageous process for commercially preparing of 2-cyanoimidazole compounds. More particularly, it relates to an efficient method of preparation of cyazofamid synthetic precursor by simultaneous conversion of aldoxime group to the corresponding cyano-derivative and reducing of N-oxygenated-imidazole ring to imidazole under mild conditions using reducing agent selected from the group consisting of metal salts of sulfur-containing derivatives in the presence of a polar organic solvent.

Abstract: It is an object of the present invention to provide a novel and advantageous process for commercially preparing of indoxacarb which is racemic or enantiomerically enriched at chiral center from its amide precursor using a new catalytic system. More particularly, it relates to an efficient method of preparation of indoxacarb which is racemic or enantiomerically enriched at chiral center from methyl-7-chloro-2,5-dihydro-2-[[[(4-tritluoromethoxy)phenyl]amino]carbonyl]-indeno[1,2-e][1,3,4]oxadiazine-4a(3H) carboxylate represented as formula (I) using methoxycarbonylation agent and metal salt of methylsulfinylmethylide in hydrocarbon solvent in the presence of organic base and phase transfer catalyst.
