title: A by-product using TIPS protection--a warning.
abstract: The TIPS derivatives of alcohols are contaminated with more or less of the diisopropyl(n-propyl)silyl derivative, which can be a major product when a bad batch of reagent is used, a large excess of reagent is used, and/or the reaction is not taken to completion.
