Overview | tributyltin hydride is a rapidly developing new reagent for modern organic synthesis. It provides a new method for the selective reduction of nitro compounds, halogen substituted compounds and the like. Applications in organic synthesis and in the preparation of special intermediates, synthesis of aldehydes, induced carbon radicals are being widely studied and applied. |
prepare | in a 1000ml reaction flask, add 300g(0.5mol) with stirring tributyltin oxide and 100g of hydrogen-containing polysiloxane or hydrogen-containing polysiloxane waste (hydrogen content 1%). The reaction system should be heated slowly (generally not more than 20 ℃, large amount should be considered to cool down), after about 1H, the temperature should be stopped, stirring should be continued for 30min, and 105~107 ℃/0.8kPa fraction should be collected by vacuum distillation, A colorless liquid, namely tributyltin hydride, was obtained. |
Use | is often used for reducing free radical reaction, and its application range is quite wide, it can not only remove the specific functional group on the compound, but also carry out addition reaction for the compound with pi bond, even high-order and stereoselective intramolecular or intermolecular coupling reactions. pharmaceutical intermediates, reducing agents. For reductive cleavage reaction, dehalogenation reaction, intramolecular group ring reaction widely used free radical reagent, can be used for reductive cleavage, free radical dehalogenation and Intramolecular free radical cyclization. |
