Methyltrioxorhenium-catalyzed oxidation of aromatic aldoximes

The first catalytic oxidation of aryl oximes to nitro compounds by means of methyltrioxorhenium and urea hydroperoxide is reported. The formation of carbamates, probably occurring through formation of nitrile oxide intermediates, has been observed from 2,6-disubstituted aryl oximes.

Thermochemical Study of Complexation of Carbamates with Isocyanates in Solution

Complexation of alkyl phenylcarbamates with isocyanates was studied calorimetrically. The compositions, stability constants, and enthalpies of formation of the complexes were determined. The stability of the complexes regularly increases with increasing electron-donor power of substituents in carbamates and electron-acceptor power of isocyanates.

Isocyanates - Part 3. Synthesis of carbamates by DMAP-catalyzed reaction of amines with di-tert-butyldicarbonate and alcohols

Carbamates are prepared by DMAP-catalyzed reaction of amines with di-tert-butyldicarbonate and subsequent trapping of the intermediate isocyanates with alcohols.
