Nickel(II) complex 1 was utilized as a sustainable catalyst for α-alkylation of arylacetonitriles with challenging secondary alcohols. Arylacetonitriles with a wide range of functional groups were tolerated, and various cyclic and acyclic secondary alcohols were utilized to yield a large number of α-alkylated products. The plausible mechanism involves the base-promoted activation of precatalyst 1 to

analogues were synthesized and their inhibitory activities againstMycobacteriumtuberculosis H37Rv determined in vitro alone and in combination with rifampicin (RIF). Some analogues showed comparable activity to verapamil and exhibited better synergies with RIF. Molecular dockingstudies of the binding sites of Rv1258c, a M. tuberculosis efflux protein previously implicated in intrinsic resistance
