Di-tert-butyl dicarbonate (Boc2O) and di-tert-butyl tricarbonate ((BocO)2CO)&nbsp; have been used as amine carbonylating reagents to obtain linear or branched aliphatic isocyanates.<br /> most of the known methods for transforming amines into isocyanates are not mild enough and furnish undefined products as a result of uncontrolled side reactions. However, 4-dimethylaminopyridine (DMAP)-catalyzed reaction with activated carbonates as C1 building blocks constitutes a convenient laboratory method for the phosgene-free isocyanation of amines. A procedure has been described whereby alkyl- and arylamines are converted into isocyanates in high yields by reaction with activated carbonates (for example, di-tert-butyl dicarbonate, Boc2O) in the presence of a catalytic amount of a nucleophilic nitrogen base at room temperature.<br /> Di-tert-butyl dicarbonate (Boc2O) is a widely used reagent for introducing protecting groups in peptide synthesis. The reaction of substituted anilines with Boc2O in the presence of a stoichiometric amount of 4-dimethylaminopyridine (DMAP) in an inert solvent (acetonitrile, dichloromethane, ethyl acetate, tetrahydrofuran, toluene) at room temperature leads to aryl isocyanates in almost quantitative yields within 10 min.
