Electrostatics and color: Massive electrostatic perturbation of chromophores by ion cluster ligands
Weiss, Robert,Puehlhofer, Frank G.
, p. 547 - 553 (2007)
The SASAPOS protocol, a general reaction sequence allowing complete exchange of various neutral ligands X in organic, elementorganic, and inorganic systems by cationic ligands L+, has been applied to a variety of pentafluorophenyl-substituted d
Rhodium(III)-catalyzed regioselective C–H nitrosation/annulation of unsymmetrical azobenzenes to synthesize benzotriazole N-oxides via a RhIII/RhIII redox-neutral pathway

A Rh(III)-catalyzed regioselective C–H nitrosation/annulation reaction of unsymmetrical azobenzenes with [NO][BF4] has been developed to achieve high-yielding syntheses of benzotriazole N-oxides with excellent functional group tolerance. Computational studies have revealed that this oxidative C–H functionalization reaction involves an interesting redox-neutral Rh(III)/Rh(III) pathway without the change of Rh oxidation state.

Direct reaction between quinone bisacetals and arylhydrazines gives azobenzenes. The presence of catalytic amounts of cerium ammonium nitrate strongly accelerates the reaction. When the bisacetal has a substituent at the 2,5-cyclohexadiene framework, only one regioisomer is formed. The method represents a simple, mild, and novel synthetic access to differently substituted azocompounds in high to excellent yield.
Diazotization of pentafluoroaniline by means of anion-catalyzed phase transfer catalysis in a hydrophobic organic solvent
Iwamoto, Hidetoshi,Sonoda, Takaaki,Kobayashi, Hiroshi
, p. 535 - 537 (2007/10/02)
Anion-catalyzed phase-transfer catalysis was successfully applied to diazotization of pentafluoroaniline in a dichloromethane-aqueous sulfuric acid two-phase system.The resulting diazonium group was coupled in situ with anisole, 1-methoxynaphthalene, and mesitylene, and replaced in situ with bromo, hydryl, and phenyl substituents under a two-phase condition.
PREPARATION AND PHOTOCHEMICAL BEHAVIOUR OF 2,3,4,5,6-PENTAFLUOROPHENYLAZO-BENZENE AND -4'-METHOXYBENZENE

, p. 61 - 72 (2007/10/02)
Pentafluoronitrosobenzene reacts readily with aniline and with p-methoxyaniline to give the corresponding 2,3,4,5,6-pentafluoroazobenzenes (1a and 1b) in good yield.Minor components detected by n.m.r. spectroscopy in the analitically pure products are sho
