Abstract: A series of phosphine‐free Ru(III)/Ru(II) complexes of NH functionalized N˄N˄N pincer ligands exhibit excellent activity for acceptorless dehydrogenative coupling (ADC) of secondary alcohols with 2‐aminobenzyl or γ‐amino alcohols to quinolines and pyridines. Ru(III) complexes [LRuCl3]… read more here.

Abstract: A solvent (2,2,2-trifluoroethanol (TFE) vs ethyl alcohol (EtOH)) switched synthesis of quinolines and pyridines is illustrated from (E)-2-(1,3-diphenylallylidene)malononitriles via a Pd(II)-catalyzed photochemical process. The active catalyst [L2Pd(0)] generated serves as an exogenous photosensitizer. The process… read more here.
