Tributyltin hydride Tributyltin hydride is an organotin compound with the formula 3 SnH. It is a colorless liquid that is soluble in organic solvents . The compound is used as a source of hydrogen atoms in organic synthesis .Synthesis and characterization The compound is produced by reduction of tributyltin oxide with polymethylhydrosiloxane :sensitive to air , decomposing to 2 O. Its IR spectrum exhibits a strong band at 1814 cm −1 for νSn-H .Applications It is a useful reagent in organic synthesis. Combined with azobisisobutyronitrile or by irradiation with light , tributyltin hydride converts organic halides to the corresponding hydrocarbon.
