Abstract: A synthetic approach to dibenzo[f,h]quinolines and their derivatives is presented via stepwise ruthenium-catalyzed C-H arylation and potassium-mediated reductive cyclodehydrogenation from 2-phenylpyridine and aryl bromides. One dibenzo[f,h]quinoline derivative is used as a bidentate ligand to prepare… read more here.

DOI: 10.3390/molecules27196274
Abstract: To discover new compounds with favorable herbicidal activity, a range of phenylpyridine moiety-containing pyrazole derivatives were designed, synthesized, and identified via NMR and HRMS. Their herbicidal activities against six species of weeds were evaluated in… read more here.
