What is Cyhexatin?
Plain description, key identifiers and synonyms
Technical cyhexatin is a nearly odorless white crystalline powder that has no true melting point but degrades to bis(tricyclohexyl)tin oxide at 121 to 131 °C which decomposes at 228 °C, a melting point of 195-198 °C is also reported. Very insoluble in water (less than 1 mg/L at 25 °C), but wettable by water. Soluble in some organic solvents (acetone 1.3 g/L, xylenes 3.6 g/L, carbon tetrachloride 28 g/L, dichloromethane 34 g/L). Used as an acaricide (an agent to kill plant-feeding mites) in almonds, walnuts, hops and some fruits.
Cyhexatin is an organotin insecticide.

How it is made
For the preparation of tricyclohexyltin chloride, the Kocheshkov redistribution reaction is not suitable. ... Two alternative routes are practiced for the manufacture of tricyclohexyltin chloride. The closely controlled reaction of cyclohexylmagnesium chloride and stannic chloride in a three-to-one molar ratio can be made to give the desired product in good yield. Another method involves 2 steps for the prepn. ... In the first step, butyltin trichloride reacts with 3 moles of cyclohexylmagnesium chloride forming butyltricyclohexyltin.

This tetraorganotin then reacts with stannic chloride under mild conditions in an inert solvent, cleaving a butyl group and yielding tricyclohexyltin chloride and butyltin trichloride. The latter is recovered and recycled. ... Tricyclohexyltin chloride is converted to the hydroxide with sodium hydroxide.
Grignard reagent is reacted with tin tetrachloride.
