A facile and high-yielding one-pot synthesis of carbamates and N,N′-disubstituted symmetrical ureas from N-acylbenzotriazoles has been devised. It is believed that, the intermediate acyl-azide undergo Curtius rearrangement and in different solvents gives different products i.e. carbamates in alcohols and N,N′-disubstituted symmetrical urea in THF.

Reductive acylation of oximes and oxime carbonates can be effected with iron powder in the presence of an acid chloride or a chloroformate to produce enamides or enecarbamates. Georg Thieme Verlag Stuttgart.
Regioselective cationic reduction of 2-aryl-1-N-(ethoxycarbonyl)enamines to 2-arylethylamine carbamates

2-Aryl-1-N-carboalkoxyenamines (enamides) are selectively reduced to the corresponding 2-arylethylamine carbamates by Et3SiH in the presence of CF3COOH in excellent yields. The reduction proceeds by addition of hydride at C-1 and the

, p. 5291 - 5293 (2007/10/03)
The titled compound effects the Lossen rearrangement on aromatic carboxylic acids, via activation by DCC or formation of the acid chlorides, to furnish the corresponding amines in excellent yields, in an essentially 'one-pot' procedure. (C) 2000 Elsevier Science Ltd.
Process for the synthesis of isocyanates and of isocyanate derivatives
-
, (2008/06/13)
The present invention relates to a process for the synthesis of isocyanates and of isocyanate derivatives. Isocyanates are obtained by reacting an organic halide with a metal cyanate in an organic medium in the presence of a catalyst consisting of a complex of nickel with at least one organic ligand, in which complex the nickel is in the zero oxidation state. A carbamate or a urea, respectively, are obtained by a subsequent reaction with a hydroxy compound or a primary or secondary amine. Isocyanates and their derivatives are used especially either as refined synthesis agents for the production of pesticides and medications, or as monomers or comonomers for the preparation of many macromolecular compounds.
