Covalent triazine frameworks were efficiently synthesized from benzyl halide derived monomers, and showed high activity in photocatalytic biomass reforming.
MgCl2 accelerates the CO2 insertion as a non-innocent additive and the one-electron reduction process as one reagent in the Ni-catalyzed carboxylation of benzyl chloride with CO2.
Diverse proteome reactivity profiles were obtained using small-molecule electrophiles. Here, we report the first proteome reactivity signature-based discrimination of 11 bacteria. Perfect differentiation of 11 bacteria can be achieved using 2 benzyl-halide probes.
Abstract
To search for novel therapeutic compounds with higher activity, a series of novel dehydroabietic acid derivatives bearing 1,3,4-oxadiazole moieties were designed and synthesized. Ten title compounds 5-dehydroabietyl-2-alkyl thio-1,3,4-oxadiazoles were synthesized by the reaction of 5-dehydroabietyl-2-mercapto-1,3,4-oxadiazole with alkyl halide or substituted benzyl halide in ethanolic KOH. All the title compounds were analyzed and characterized by means of IR, UV-vis, EI-MS, 1H-NMR, 13C-NMR, and elemental analysis. The preliminary herbicidal assay showed that almost all of the compounds exhibited an excellent growth inhibition to rape (Brassica campestris) and a certain inhibition to barnyard grass (Echinochloa crusgalli L.) at a concentration of 100 μg ml-1.
