Dibutyltin oxide, or dibutyloxotin, is an organotin compound with the chemical formula (C4H9)2SnO. It is a colorless solid that, when pure, is insoluble in organic solvents. It is used as a reagent and a catalyst. See more The structure of diorganotin oxides depends on the size of the organic groups. For smaller substituents, the materials are assumed to be polymeric with five-coordinate Sn centers and 3-coordinate oxide centers. The … See more In organic synthesis, among its many applications, it is particularly useful in directing regioselective O-alkylation, acylation, and sulfonation reactions for diols and polyol. DBTO has been used in the regioselective tosylation (a specific type of sulfonation) of certain See more Otera's catalyst See more
