Abstract
The application possibilities of the in situ reactions of trichloroacetyl isocyanate (TAI method) to structural assignment of alcohols by means of 1H NMR spectroscopy are critically evaluated. The possibilities of TAI acylations in various solvents are demonstrated and the reactivity of various functional groups, potentially complicating or extending the applications of TAI, is discussed. In addition to their use in structural analysis such reactions also can serve as model experiments for preparative purposes.
