The emission anisotropics of the fluorescence of the prolate molecules 2[4(N,N-dimethyloamino)a styrylo]benzothiazol and 2[4(N,N-dimethyloamino)a styrylojbenzoksazol in solvents of different viscosities were measured, yielding information about the rotational motion of the molecules. The non-linear dependence of 1/r on T\r\ was confirmed. On the basis of a comparison of experimental and quantum...
The Pd-benzothiazol-2-ylidene complex I was found to be a chemoselective catalyst for the Tsuji-Trost allylation of active methylene compounds carried out under neutral conditions and using carbonates as allylating agents. The proposed protocol consists in a simplified procedure adopting an in situ prepared catalyst from Pd2dba3 and 3-methylbenzothiazolium salt V as precursors. A comparison of ...
6-Nitro- and 6-amino-benzothiazoles bearing different chains in position 2 and their corresponding anthranilic acid derivatives were investigated for their in vitro antiparasitic properties against parasites of the species Leishmania infantum and Trichomonas vaginalis compared to their toxicity towards human monocytes. Biological investigations established that the antiprotozoal properties depe...
