Condensation of 2-(2′-aminophenyl)benzoxazole with p-toluenesulfonyl chloride and phenyl isocyanate yields two new anion sensors (TABO and PUBO), which can undergo excited-state intramolecular proton transfer (ESIPT) upon excitation. For the acid receptor

We first report the direct ortho C-H amidation of arenes with azides by using a novel and inexpensive RuHCl(CO)(PPh3)3 catalyst. The reaction proceeds efficiently in high yield over a broad range of substrates without requirement of any additional silver salt or additive.

Iridium-catalyzed direct ortho C-H amidation of arenes has been shown to work well with sulfonyl- and aryl azides as the nitrogen source. The reaction proceeds efficiently with a broad range of substrates bearing conventional directing groups with excellent functional group compatibility under mild conditions. In addition, substrates forming not only 5- but also 6-membered iridacycle intermediates undergo the C-H amidation with high selectivity.
