Chemische Eigenschaften
clear colorless to slightly yellow liquidVerwenden
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.Application
Trichloroacetyl Isocyanate is used as an in situ derivatizing reagent for characterization of alcohols, glycols, phenols, and amines by nuclear magnetic resonance (NMR).It has been reported in the literature that it can be used for the preparation of cefuroxime axetil.synthetische
Trichloroacetyl isocyanate can be obtained by reacting 2,2,2-trichloroacetamide with oxalyl chloride.Procedure: A reaction mixture of 2,2,2-trichloroacetamide (100 g, 616 mmol, 1.0 eq) in (COCl)2 (725 g, 5.71 mol, 500 mL, 9.28 eq) was heated to 70°C for 24 hours. The reaction mixture was concentrated under vacuum. To the mixture was added 1,2,4-trichlorobenzene (500 mL) and (COCl)2 (116 g, 914 mmol, 80 mL, 1.48 eq). The reaction mixture was stirred at 100°C for 5 hours. Heat to 125°C for 15 hours. The mixture was then heated to 140°C for 5 hours. The reaction mixture was distilled under water pump (72°C-76°C fractions) to give trichloroacetyl isocyanate (60 g, 319 mmol, 52% yield) as a colorless oil.
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.Trichloracetylisocyanat Upstream-Materialien And Downstream Produkte
