Butylchlorodihydroxytin - Reaction / Application on synthetic works

The synonyms of butylchlorodihydroxytin are butyltin(IV) chloride dihydroxide, butyldihydroxidetin(IV) chloride, butyltin(IV) chloridedihydroxide, n-butylchlorotin (IV) dihydroxide, n-butyltin chloride dihydroxide, butyltin chloride dihydroxide, and n-butyltin dihydroxy chloride

Butylchlorodihydroxytin is an important Tin-based catalyst to synthetize polymers and organotin substituted products. [1-4].

Example 1

The product was prepared by refluxing N′-(2-hydroxy-3-methoxybenzylidene) formohydrazide 0.58 g (3.0 mmol) with dioctyltin (IV) oxide 1.09 g (3.0 mmol) in 100 mL dry toluene in 1:1 ratio. The water formed during the reaction was removed by Dean–Stark apparatus. The yellow solution obtained was rotary evaporated under reduced pressure and the solid formed was recrystallized from chloroform and n-hexane (4:1) mixture

Example 2

The product was prepared by refluxing N1′,N6′-bis(5-bromo-2-hydroxybenzylidene) adipodihydrazide 0.81g (1.5mmol) and dioctyltin (IV) oxide 1.09g (3.0mmol) in 100mL dry toluene in 1:2 ratio. The water formed during the reaction was removed by Dean-Stark apparatus. The yellow solution obtained was rotary evaporated under reduced pressure. A viscous liquid product was obtained.

Example 3

The product was prepared byrefluxing N1′,N6′-bis(2-hydroxybenzylidene) adipodihydrazide( 0.57 g, 1.5 mmol) with di-n-octyltin (IV) oxide(1.09 g, 3.0 mmol) in 100 mL dry toluene in 1:2 ratio. The water formed during the reaction was removed by Dean–Stark apparatus. The yellow solution obtained was rotary evaporated under reduced pressure viscous liquid product that was obtained. Yield: 72 percent. The product can also be prepared in the same way, using following precursors quantities: N1′,N6′-bis(2-hydroxybenzylidene) adipodihydrazide (0.57 g, 1.5 mmol) andbutyldihydroxidetin(IV) chloride (0.73 g, 3.0 mmol) werereacted in a 1:2 ratio. Solid product was recrystallized froma chloroform and n-hexane (4:1) mixture. Yield 75percent. mp 130–132 °C.
