bactericidal activity with MIC99 values <10 μM against drug-sensitive Mycobacterium tuberculosis and MDR-TB, were identified. These compounds demonstrate no detectable drug resistance. The mode of action and target deconvolution studies suggest that these compounds inhibit mycobacterial growth by interfering with cellenvelopebiogenesis, specifically late-stage mycolic acid biosynthesis.

Reductive elimination reactions of the cyclometalated platinum-(IV) compounds [PtMe2ClC6H4CH=NCH2(4-ClC6H4)}L] and [PtMe2BrC6H4CH=NCH2(C6H5)}L] (L = SMe2, PPh3) to form C-sp3-C-sp2 bonds, followed by either exclusive C H bond activation (L = SMe2) or competition between C-sp2-H and C-sp3-H bond activation (L = PPh3), are reported. Isomerization to give endo products instead of the expected exo complex was observed for the ligand C6H4CH=NCH2(2-BrC6H5), and formation of an endo six-membered platinacycle occurs for the ligand 2,4,6-Me3C6H2CH=NCH2(2-BrC6H4).

A number of isomeric N-benzylbenzalimine palladium(II) complexes of the type [P·CH2Ph]2 (with CN endo to the palladocycle) and [PC(CH3Ph]2 (with CN exo to the palladocycle), have been prepared and charcterised by 1H and 13C NMR methods. The crystal structures of two analogous monomeric acac complexes, synthesized independently by oxidative addition of o-BrC6H4CH2NCH · Ph to Ph to Pd(dibenzylideneacetone)2

Electrification of thermal chemical processes could play an important role in creating a more energy efficient chemical sector. Here we demonstrate that a range of MLC catalysts can be successfully electrified and used for imine formation from alcohol precursors, thus demonstrating the first example of molecular electrocatalytic C–N bond formation.This novel concept allowed energy efficiency to be increased
