ABSTRACT:
S-tricyclohexyltin-O,O-diisopropyl dithiophosphate, a useful miticide, is produced by reaction of tricyclohexyltin chloride with diisopropyl dithiophosphoric acid and a base selected from the group consisting of alkali metal hydroxides and ammonium hydroxide in a two-phase aqueous-organic system. The reaction may be conducted with or without the use of a solvent. In the case of strong alkali metal hydroxides such as sodium hydroxide the reaction is preferably conducted at a pH of about 7 or less.
