In recent years, merging different types of catalysis in a single pot has drawn considerable attention and these catalytic processes have mainly relied upon metals. However, development of a completely metal free approach integrating organic redox and organic Lewis acidic property into a single system has been missing in the current literature. This study establishes that a redox active phenalenyl

Mg for B: An atom‐economical one‐potsynthesis by direct magnesium insertion in the presence of B(OBu)3 and LiCl allows a broad range of functionalized (hetero)aryl and alkenyl bromides to be converted into magnesium diorganoboronates 2, which undergo Suzuki–Miyauracross‐couplingreactions with various aryl (pseudo)halides (see scheme). Both aryl groups of 2 are transferred and furnish the products
N-Biphenyl(substituted methyl) aminocycloalkanecarboxamide derivatives are bradykinin B1 antagonists or inverse agonists useful in the treatment or prevention of symptoms such as pain and inflammation associated with the bradykinin B1 pathway.
