catalyst, the first example of β-arylation of secondary alcohols with aryl bromides has been developed via borrowing hydrogen catalysis enabled by an MPV type hydrogen transfer process. In addition, the enantioconvergent version of the reaction has also been realized under the catalysis of Pd and Ru, allowing for the transformation of racemic secondary alcohols into enantioenriched chiral alcohols with good

Let's get multicatalytic! A Ni0 catalyst complexed with a biaryldialkyl monophosphine ligand facilitates CC bond formation between styrenylepoxides and aryl boronicacids (see scheme). X‐ray analysis of a catalytically active nickel/ligand complex supports a redox pathway involving CO bond activation. A variety of α‐substituted alcohols were generated with good reaction efficiency by a multicatalytic

this study was to investigate 4,5-diaryl isoselenazoles as multiple target non-steroidal anti-inflammatory drugs (MTNSAIDs) which can intervene into the inflammatory processes via different mechanisms of action creating a new class of compounds. Here we describe the synthesis of COX/LOX inhibitors which additionally reduce the level of reactive oxygen species, such as hydroxylradicals which are well
