일반 설명

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.

애플리케이션

Trichloroacetyl isocyanate was used in catalytic one-pot dehydrative glycosylation of 1-hydroxy carbohydrate. It was also used as a reagent for the conversion of alcohols to carbamates†.
