As an example the organic synthesis of tributyl-[(Z)-5-phenyl-2-penten-2-yl]stannane: A Grignard reagent is prepared from magnesium turnings and (Z)-2-bromo-5-phenyl-2-pentene in dry tetrahydrofuran and titrated with tributyltin chloride until the solution decolourises. The resulting solution is stirred at room temperature for 1 hour and the solvent is removed in a rotavapor. Diethyl ether is added and the ether extract is washed with brine and filtered and the ether evaporates in a rotavapor. The crude product is kugelrohr distilled ...

Organotin - Preparation of organotin compounds

reaction of a grignard reagent with tin halides for example tin tetrachloride
Wurtz reaction like coupling of alkyl sodium compounds with tin halides yields tetraorgano tin compounds
by an exchange reaction of tin halides with organo aluminium compounds (AlR₃)
triorganotin halides are prepared in the Kocheshkov redistribution reaction

As an example the organic synthesis of tributyl-[(Z)-5-phenyl-2-penten-2-yl]stannane:

A Grignard reagent is prepared from magnesium turnings and (Z)-2-bromo-5-phenyl-2-pentene in dry tetrahydrofuran and titrated with tributyltin chloride until the solution decolourises. The resulting solution is stirred at room temperature for 1 hour and the solvent is removed in a rotavapor. Diethyl ether is added and the ether extract is washed with brine and filtered and the ether evaporates in a rotavapor. The crude product is kugelrohr distilled to yield tributyl-[(Z)-5-phenyl-2-penten-2-yl]stannane as a colourless oil.
