Fluoride anion was found to promote monoalkylation reaction of diols by the stannylene acetal method, and selective monoalkylation of various acyclic diols was accomplished in good yields under mild conditions by employing this new method. Functional groups such as carboxylic acid ester, carboxamide, carbamate, nitrile, alkyl chloride, and ether were not affected under the reaction conditions.
