| titleOfInvention | Production of salithion |
| abstract | PURPOSE: To economically and advantageously obtain the titled salithion useful as an insecticide for fruit trees and vegetables, by reacting a specific thiophosphoric acid chloride with a boron hydride compound in an aqueous solution of an alkali. n CONSTITUTION: (A) 0-methyl 0-2-formylphenylthiophosphoric acid chloride expressed by formula I is reacted with (B) a boron hydride compound expressed by the formula MBH 4 (M is alkali metal atom) (e.g. sodium boron hydride) in (C) an aqueous solution of an alkali (e.g. sodium carbonate), e.g. at -20W50°C for 1W24hr, to provide 2-methoxy-4H-1,8,2-benzodioxaphosphorin 2-sulfide expressed by formula II. Furthermore, e.g. the component (A) is preferably obtained by reacting salicylaldehyde expressed by formula III with methyl thiophosphoric acid dichloride expressed by formula IV in an aqueous solution of an alkali. n COPYRIGHT: (C)1988,JPO&Japio |
