Visible Light-Induced Regioselective Cycloaddition of Benzoyl Azides and Alkenes to Yield Oxazolines
Bellotti, Peter,Brocus, Julien,El Orf, Fatima,Selkti, Mohamed,K?nig, Burkhard,Belmont, Philippe,Brachet, Etienne
supporting information, p. 6278 - 6285 (2019/05/24)
Visible light catalysis allows the regioselective synthesis of oxazolines in high yields. The mild photosensitized manifold leverages the intermolecular formation of oxazolines with a wide functional group tolerance on both benzoyl azides and alkenes part

experimental part, p. 1587 - 1593 (2008/10/09)
The preparation and use of an azide-containing monolithic reactor is described for use in a flow chemistry device and in particular for conducting Curtius rearrangement reactions via acid chloride inputs. The Royal Society of Chemistry 2008.
Thiol on silica as a 'catch and release' support for isocyanates to afford ureas

Silica-bound thiocarbamates were prepared by Curtius rearrangement of carboxylic acids in the presence of thiol on silica gel. The solid supported thiocarbamates were found to be stable isocyanate equivalents, which upon treatment with amines efficiently afforded di- and tri-substituted ureas. The urea products released from the catch and release support were, in the majority of cases, greater than 95% pure and required no further work up.
Hypervalent iodine in synthesis. Part 54: One-step conversion of aryl aldehydes to aroyl azides using a combined reagent of (diacetoxyiodo)benzene with sodium azide
Chen,Chen
, p. 7361 - 7363 (2007/10/03)
Aroyl azides are readily prepared from the corresponding aryl aldehydes with the aid of (diacetoxyiodo)benzene (DIB) and sodium azide in high yields. (C) 2000 Elsevier Science Ltd.
Modified Pyridinium Chlorochromate Oxidation of Aldehydes to Carbamoyl Azides/Acyl Azides or Carboxylic Acids
Reddy, P. Satyanarayana,Yadagiri, Pendri,Lumin, Sun,Shin, Dong-Soo,Falck, J. R.
, p. 545 - 552 (2007/10/02)
Aldehydes are transformed into carbamoyl azides/acyl azides by pyridinium chlorochromate in the presence of sodium azide.Comparable oxidations modified with sodium cyanide generate carboxylic acids from simple aliphatic aldehydes whereas conjugated aldehydes are undeactive.
