Reacts with alcohols to give tri-n-butylstannyl ethers which, for simple alcohols, are very susceptible to hydrolysis: Synthesis, 56 (1969); J. Organomet. Chem., 110, C57 (1976). In combination with bromine or NBS, allylic, benzylic and secondary alcohols are oxidized to carbonyl compounds, enabling the selective oxidation of secondary, in the presence of primary, alcohols: Bull.
