A novel C–N coupling of various arylamines with dialkyl azodicarboxylates under metal-free conditions for the rapid assembly of carbamates has been achieved. This established protocol features mild reaction conditions, simple operation, broad substrate scope, moderate to excellent yields and good tolerance of functional groups. Moreover, the potential synthetic utility of products was exemplified by

An aqueous cleaning composition is provided which includes an amido or imido organic peroxyacid having water solubility of less than 1 x 10⁻⁴M, a structuring surfactant and a pH-adjusting system for maintaining pH from 3.5 to 8.5 during storage and, upon dilution with a wash water, causing pH to rise by at least 0.5 pH units.

thermolysis at 200 °C gave azepino-indoles (48) and (51), the first examples of ringexpansion by an arylnitrene of benzenerings with electron-with drawing substituents. Also reported are syntheses of 3- and 4-(2-azidobenzyl)pyridines (38) and (39), and of 2-(2-azidobenzyl)thiazole (40); decomposition of these azides gave mainly polymers.
