Volatile amine vapors are toxic and corrosive irritants and can cause serious health problems. In addition, the biologically amine vapor produced by microorganisms is also an important indicator of food spoilage. Therefore, the development of simple, sensitive, and selective amine vapor detection methods is of great significance. A new ESIPT-based fluorescent probeHBTAchas been developed as a rapid, highly sensitive, and selective sensor for amine vapors in this work. TheHBTAcsensor exhibits an obvious fluorescence turn-on response at 514 nm toward amine vapors with a large Stokes shift (180 nm), and a low detection limit (12.7 ppm). Taking advantage of its portability and high sensitivity to amine vapors, theHBTAcsensor can be used for food spoilage monitoring by detecting volatile amines produced by microbial growth. Finally, agar gels based on theHBTAcprobe were fabricated, which could act as a solid optical sensor to conveniently and efficiently detect amine vapors.

A novel strategy for direct aryl hydroxylation via Pd-catalysed Csp2-H activation through an unprecedented hydroxyl radical transfer from 1,4-dioxane, used as a solvent, is reported with bio relevant and sterically hindered heterocycles and various acyclic functionalities as versatile directing groups.

A chelation-assisted Pd-catalyzed ortho-acyloxylation reaction of the 2-arylbenzo[d]thiazole is described via sp2 C-H bond activation. A wide substrate scope with good functional group tolerance has been demonstrated, affording mono- or diacyloxylation products in moderate to good yields. This method is an alternative route for the preparation of 2-arylbenzo[d]thiazole derivatives via a C-H activation mechanism.

Compounds having either of the structures SPC1 Have strong acaricidal activity, in which R is a phenyl or naphthyl group, or phenyl with certain designated substitution. Thus, mites may be controlled on such crops as cotton by applying such compounds as 2-(1-naphthyl)benzothiazoline or 2-(5-t-butyl-2-hydroxyphenyl)benzothiazole.
