A new fluorescent probe for gasotransmitter H2S: High sensitivity, excellent selectivity, and a significant fluorescence off-on response

A fluorescent off-on probe for H2S was exploited by coupling the azide-based strategy with the excited-state intramolecular proton transfer (ESIPT) sensing mechanism, which exhibits a considerably high fluorescence enhancement (1150-fold), an e

Antitumor benzothiazoles. Part 2. Formation of 2,2'-diaminobiphenyls from the decomposition of 2-(4-azidophenyl)benzazoles in trifluoromethanesulfonic acid

Decomposition of 2-(2-azidophenyl)- and 2-(3-azidophenyl)-benzothiazoles in trifluoromethanesulfonic acid generates ?-carbocations.These reactive intermediates have been trapped by triflate anion with the nucleophile substituting para to the original azido group to yield triflate-substituted arylamines. 2-(4-Azidophenyl)-benzothiazoles and -benzoxazoles behave differently: triflate-substituted arylamines are accompanied by symmetrical or unsymmetrical benzazolyl-substituted 2,2'-diaminobiphenyls as major products.These biphenyls have been identified by their characteristic 1H and 13C NMR spectra. 2,2'-Diaminobiphenyls are formed by initial C-C coupling interactions between the ?-carbocations and undecomposed 2-(4-azidophenyl)benzazoles and not by benzidine-type rearrangements as originally proposed.Symmetrical 2,2'-diaminobiphenyls have been oxidized by (diacetoxyiodo) benzene to give novel benzazolyl-substituted benzocinnolines.

Competitive Cyclisations of Singlet and Triplet Nitrenes. Part 9. 2-(2-Nitrophenyl)-benzothiazoles and -benzimidazoles

2-(2-Nitrophenyl)benzothiazole, produced by deoxygenation of the corresponding nitro-compound or by thermolysis or photolysis of the related azide, gives indazolobenzothiazole by attack on the benzothiazole nitrogen.Similar attack of the nitrene in 2-(2-nitrophenyl)benzimidazoles gives benzimidazoindazoles in good yield.However, with an appropriate 1-substituent in the benzimidazole (e.g.Me or CHMe2) the nitrene in its triplet state (generated by acetophenone-sensitised photolysis or by thermolysis of the azide bearing a 4-dimethylamino-group) preferentially attacks this substituent giving benzimidazoquinazolines.
