experimental part, p. 1149 - 1151 (2012/08/07)
A simple and mild one-pot procedure for the synthesis of carbamoyl azides from acyl chlorides utilizing a combination of tetrachlorosilane and sodium azide in acetonitrile at ambient temperature is reported. Under gentle heating 1-aryltetrazolin-5- ones were also obtained in one-pot process presumably via a [3 + 2] cycloaddition step.
An unplanned synthesis of symmetrical 1,3-disubstituted ureas
Perveen, Shahnaz,Mustafa, Sana,Khan, Khalid Mohammed
experimental part, p. 229 - 234 (2011/10/05)
When urea derivatives (N-aryl-N′, N'-dialkyl urea) or (N-aryl-N'-alkyl/arvl urea) la-lu react with diethylcarbamyl chloride at 50-60°C symmetrical 1,3-disubstituted ureas 2a-2f were furmed as major products instead of forming ployureas.
