ABSTRACT:
A process for producing tricyclohexyl tin derivatives, consists of a first phase in which Grignard reagent and tin tetrahalogenide are caused to react by feeding them into a reaction vessel in a molar ratio of 3:1, and a second phase in which after hydrolysis and anhydridization of the condensation mass, further Grignard reagent is added in an amount such as to maintain the total molar ratio, between the Grignard reagent and the tin tetrahalogenide, between 3.5:1 and 3.9:1.
