New and simple synthesis of acid azides, ureas and carbamates from carboxylic acids: Application of peptide coupling agents EDC and HBTU
Sureshbabu, Vommina V.,Lalithamba,Narendra,Hemantha
experimental part, p. 835 - 840 (2010/06/20)
Conversion of carboxylic acids into acid azides using peptide coupling agents, EDC and HBTU is described. The procedure is efficient, practical and applicable to a diverse range of carboxylic acids including N-protected amino acids. Using the same reagents, one-pot synthesis of ureas, dipeptidyl urea esters and carbamates from acids has also been achieved. The Royal Society of Chemistry 2010.

ARE THIOPHENES ATTACKED AT SULPHUR BY NITRENES?
Meth-Cohn, Otto,Vuuren, Gerda van
, p. 1105 - 1108 (2007/10/02)
Ethyl azidoformate is shown to attack a range of thiophenes at sulphur giving transient S,N-ylides which can be trapped with acenaphthylene as adducts; thiophene yields self-trapped products also.
