General description
Dibutyltin(IV) oxide is an organotin compound that is commonly used as a Lewis acid catalyst in organic synthesis. For instance, it can be used for the formation of carbon-carbon bonds through coupling reactions and in the preparation of esters from carboxylic acids and alcohols. It also finds use in allylation reactions, cycloaddition reactions, and ring-opening polymerizations.

For partial phenylcarbamoylation of the hydroxy-groups of ribonucleosides, dibutyltin oxide--phenyl isocyanate system was found to be surperior to the bis(tributyltin) oxide--phenyl isocyanate system from the standpoint of reaction procedures including isolation of the products; the reaction was proved to occur

Dibutyltin oxide-mediated regioselective chloroacetylation of methyl 1-thio-beta-xylobioside, followed by treatment of the product with 4-methylbenzoyl chloride-pyridine, gave methyl 4-O-chloroacetyl-2,3-di-O-(4-methylbenzoyl)-beta-D-xylopyranosyl-(1-->4) -2.3-di - O-(4-methylbenzoyl)-1-thio-beta-D-xylopyranoside (18) in 70% yield. Coupling of 18 with benzyl alcohol afforded the disaccharide benzyl beta-glycoside, which was O-dechloroacetylated
