A carbene-catalyzed oxidative cycloaddition reaction is developed for efficient access to multi-functionalized 2-phenylbenzothiazoles. A broad scope of heavily substituted arenes bearing 2-benzothiazole groups have been prepared in good to excellent yields. The remote C(sp2)–H bond in the substituted arene products can be activated by Pd catalysts in regio-selective fashion with the direction of the 2-benzothiazole groups.

A series of novel BF2 complexes, bearing a five-membered heterocyclic ring (with X = NMe, O, and S), were synthesized and characterized with a focus on the influence of atom exchange on the photophysical properties of both unsubstituted and dim

Stable aromatic nitrile oxides underwent a 1,3-dipolar cycloaddition reaction with 1-iodo-4-(prop-2-yn-1-yloxy)benzene to afford the expected isoxazoles in very good yields as single regioisomers. The formation of the 5-substituted isoxazoles is in agreement with frontier orbital theory. The reductive cleavage of the N–O bond followed by complexation with BF3·Et2O afforded the corresponding boron complexes, which were further derivatized with a triple bond for click chemistry applications. The photochemical behavior and the fluorescence properties of the derivatives were investigated and discussed, taking theoretical calculations into consideration.
Benzothiazole-enamide-based BF2 complexes: Luminophores exhibiting aggregation-induced emission, tunable emission and highly efficient solid-state emission

A series of benzothiazole-enamide-based boron difluoride complexes (Borebt1-6) were synthesized and characterized. These new luminophores were demonstrated to possess aggregation-induced emission, tunable, substituent-dependent emission profiles and large Stokes shift in solution. In the solid state, Borebt1-6 exhibited intense emission with high quantum yields of 0.21-0.37. The photophysical properties and AIE characteristics of these compounds were rationalized through X-ray crystal analysis, electrochemical studies and theoretical calculations. Furthermore, Borebt3-6 were capable of sensing acidic gas by reversible changes of emission, which may potentially serve as solid-state fluorescent sensors for acidic vapors. This journal is
