Beschreibung

Allgemeine Beschreibung

Conformational stability and vibrational IR and Raman spectra of trichloroacetyl isocyanate has been investigated. Trichloroacetyl isocyanate is commonly employed as in situ derivatizing reagent for the ¹³C NMR studies of alcohols, phenols and amines. It undergoes 1,5-cycloaddition reaction with anhydro-2-deoxy-D-erythro- and -L-threo-pent-1-enitols and 1,5-anhydro-2-deoxy-D- and -L-arabino-hex-1-enitols to yield [2+2] and [4+2] cycloadducts.

Anwendung

Reagent for the conversion of alcohols to carbamates.
