The cyclocondensation of 2-aminothiophenol and carboxylic acids to give benzothiazoles has been carried out under mild conditions using tetrabutylammonium bromide (TBAB) as the reaction medium and triphenyl phosphite as the catalyst. Shorter reaction times, rapid isolation of the products, and excellent yields are advantages of this method. The reaction is found to be general and quite tolerant to

thus can provide an efficient solution to this challenge. Here, we report the design, synthesis and biologicalevaluation of ratiometric sodium selenite fluorescent probe (HBTN-Se) for quantitative ratiometric fluorescence imaging of sodium selenite concentration fluctuations in living cells. A strategy for sodium selenite quantification has been achieved effectively through using a highly selective

A new tunable luminescent family of heterocyclic aromatic compounds containing boron has been prepared and characterized through NMR spectroscopy, mass spectrometry, absorption and fluorescence spectroscopy as well as structural study using single crystal X-ray crystallography. Spectroscopic properties of the new compounds were also studied using DFT and TDDFT computational models that showed very
