A novel and highly selective conversion of alcohols, thiols, and silyl ethers to azides using the triphenylphosphine/2,3-dichloro-5,6- dicyanobenzoquinone(DDQ)/n-Bu4NN3 system
Iranpoor, Nasser,Firouzabadi, Habib,Akhlaghinia, Batool,Nowrouzi, Najmeh
, p. 3291 - 3294 (2004)
Alcohols, thiols, and silyl ethers are converted into alkyl azides in good to excellent yields by treatment with PPh3/DDQ/n-Bu 4NN3 in CH2Cl2 at room temperature. The method is highly selective for 1°
THE IR AND RAMAN SPECTRA AND CONFORMATIONS OF CYCLOHEXYL AZIDE
Suelzle, D.,Gatial, A.,Karlsson, A.,Klaeboge, P.,Nielsen, C. J.
, p. 207 - 214 (1988)
Cyclohexyl azide was synthesized and the vibrational spectra recorded in several phases including: liquid at various temperatures, amorphous and crystalline at 90 K and high pressure crystal at ca. 60 kbar.Additional IR spectra were recorded in argon and

Carbon isotope labeling is a traceless technology, which allows tracking the fate of organic compounds either in the environment or in living organisms. This article reports on a general approach to label urea derivatives with all carbon isotopes, including14C and11C, based on a Staudinger aza-Wittig sequence. It provides access to all aliphatic/aromatic urea combinations.

Biaryls have widespread applications in organic synthesis. However, sequentially polysubstituted biaryls are underdeveloped due to their challenging preparation. Herein, we report the synthesis of dissymetric 2,3,2′,3′,4-substituted biaryls via pericyclic reactions of cyclic diaryl λ3-bromanes. The functional groups tolerance and atom economy allow access to molecular complexity in a single reaction step. Continuous flow protocol has been designed for the scale-up of the reaction, while postfunctionalizations have been developed taking advantage of the residual Br-atom.
