The use of hemilabile pyridine-hydrazone N,N-ligands allows the highly selective Ir-catalyzed ortho,ortho'-directed diborylation of aromatic N,N-dimethylhydrazones in near-quantitative yields. One-pot sequential Suzuki-Miyaura cross-coupling with different aryl bromides provides a short entry to unsymmetrically substituted 2,6-diarylbenzaldehyde derivatives.

Hydrogen peroxide oxidation of N,N-dimethylhydrazones 1 promoted by title reagents has been investigated. Depending on the substrate nitrile 2 and/or amide 3 accompanied with carboxylic acid 4 and parent carbonyl compounds 5 were obtained. Formation of nitriles 2 with H2O2-acetonitrile system is limited for a few more active substrates. The mechanism of the reaction, based on generated in situ peroxyiminoacetic acid, is presented. A broad spectrum of aliphatic, unsaturated and aromatic nitriles 2 was obtained by oxidation of corresponding N,N-dimethylhydrazones 1 with hydrogen peroxide in the presence of poly(bis-9,10-anthracenyl) diselenide (PADS) (7) as catalyst.
