Abstract: This review summarizes the intermolecular PdII-catalyzed dehydrogenation procedures leading to regioselective coupling of alcohols with (hetero)arenes bearing tethered coordinating groups. Unusual oxidative conditions of catalyst regeneration are required, and the optimum oxidant varies with the… read more here.

DOI: 10.1021/jacs.2c02102
Abstract: Conventional chemical and even electrochemical Birch-type reductions suffer from a lack of chemoselectivity due to a reliance on alkali metals or harshly reducing conditions. This study reveals that a simpler avenue is available for such… read more here.

DOI: 10.1055/s-0040-1707327
Abstract: Owing to the importance of arene moieties in organic chemistry, methods for arene construction attract great attention. Besides the traditional substitution strategy from pre-existing arenes, the straightforward formation of arene cores can also provide significant… read more here.
