Efficient catalytic one‐step synthesis of substituted quinoline derivatives using newly synthesized Ru(II) half‐sandwich complexes of the type [Ru(η6‐p‐cymene)Cl(L)] (L = pyrrole‐2‐aldehydehydrazones) under mild conditions is described. The synthesized complexes exhibit excellent catalytic activity towards the coupling of 2‐amino alcohol with functionalized ketones and secondary alcohols in the optimal

A systematically generated series of hydrazones were analyzed as potential inhibitors of anthrax lethal factor. The hydrazones were screened using one UV-based and two fluorescence-based in vitro assays. The study identified several inhibitors with IC50 values in the micromolar range, and importantly, significant differences in the types of inhibition were observed with the different assays.

titanium(IV) complexes of the general formulae L2TiCl2 [L− = benzoyl and mono- chlorobenzoylhydrazones of 2-furaldehyde(FBH-H and FC1BH-H), 2-thiophenaldehyde(TBH-H and TC1- BH-H), 2-pyrrolaldehyde(PBH-H and PC1BH-H)] and L′TiCl3 [L′ = benzoyl and monochlorobenzoyl- hydrazones of di-2-pyridylketone (DBH-H and DC1BH-H)] have been prepared and characterised by various physicochemical methods. All ligands appear

interaction resulted in the formation of a pseudo-octahedral geometry with the iridium center. The iridium complexes 1–4, which are stable in the presence of air and moisture, exhibit significant catalyst performance in the N-alkylation reactions of hydrazides under gentle reaction conditions. This iridium complex catalyzes various types of alcohols to undergo N-alkylation reactions with acyl hydrazides via a
