A convenient method for the synthesis of symmetrical azobenzenes is reported. This one-step procedure involves treatment of anilines with N-chlorosuccinimide (NCS) and organic base 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU). A wide range of commercially available substituted anilines readily participate in this reaction to produce the corresponding azobenzenes in moderate-to-excellent yields in minutes

stable cis configurations resulting from fluorination of positions ortho to the azo group are reported that can differentially regulate the activity of carbonic anhydrase in the trans and cis configurations. These fluorinated probes each use two distinct visible wavelengths (520 nm and 410 nm or 460 nm) for isomerization with high photoconversion efficiency. Correspondingly, the cisisomer of these

A solventless mechanochemical methodology for the oxidation of electron-poor fluorinated anilines to the corresponding symmetrical azo compounds has been developed. In this process phenyliodine(III)diacetate and inexpensive calcium hypochlorite demonstrate to be good oxidants, providing the desired fluorinated azobenzenes in satisfactory yields, within short reaction times and avoiding the use of environmental
The invention relates to a process for preparing fluorinated anilines starting from the corresponding chlorinated anilines, and also to the use of the fluorinated anilines.
