A new efficient copper-catalyzed intramolecular amination reaction has been developed to readily synthesise a wide variety of multi-substituted 2H-indazole and 1H-pyrazole derivatives from easily accessible starting materials under mild conditions. A highly selective ligand for estrogen receptor β was prepared in three steps by employing this method. The Royal Society of Chemistry 2011.
Substituent effects on the lifetimes and reactivities of arylnitrenium ions studied by laser flash photolysis and photothermal beam deflection

Photolysis of 5-substituted-N-tert-butyl-3-methylanthranilium ion produces transient N-tert-butyl-(2-acetyl-4-substituted) phenylnitrenium ions. This is confirmed by identification of the stable products, transient absorption experiments, and photothermal
Pyrolysis of aryl azides. XIII*Conformational effects on the ability of carbonyl as a neighbouring group
Dyall, Leonard K.,Ferguson, John A.,Jarman, Tony B.
, p. 1197 - 1202 (2007/10/03)
Our previous claim, 1 that locking an ortho carbonyl group into a favourable conformation causes very large increases in the rate of thermolysis of aryl azides, has been reexamined. In 8-azido-5-methoxy-1-tetralone the rate advantage over an azide with a
