A versatile access to pyridazines with tethered imidazolium groups-new precursors for mono- and binucleating NHC/pyridazine hybrid ligands

One or two imidazolium groups have been attached to the 3- and 6-positions of the pyridazine heterocycle, providing valuable precursors for mono- and binucleating NHC/pyridazine hybrid ligands. For N-methyl imidazole with specific backbone substituents an unexpected methyl group transfer is observed, which defines the scope of the synthetic procedure. H-Bonding patterns in the solid state are elucidated by X-ray crystallography for seven chloride or PF6- salts of the new compounds.

Nickel-Catalyzed Thiolation of Aryl Halides and Heteroaryl Halides through Electrochemistry

Transition-metal-catalyzed coupling reactions are useful tools for synthesizing aryl sulfur compounds. However, conventional transition-metal-catalyzed thiolation of aryl bromides and chlorides typically requires the use of strong base under elevated reaction temperature. Herein, we report the first examples of nickel-catalyzed electrochemical thiolation of aryl bromides and chlorides in the absence of an external base at room temperature using undivided electrochemical cells.

Efficient Phosphorus-Free Chlorination of Hydroxy Aza-Arenes and Their Application in One-Pot Pharmaceutical Synthesis

The chlorination of hydroxy aza-arenes with bis(trichloromethyl) carbonate (BTC) and SOCl2 has been effectively performed by refluxing with 5 wt % 4-dimethylaminopyridine (DMAP) as a catalyst. Various substrates are chlorinated with high yields. The obtained chlorinated aza-arenes can be used directly with simple workup for succedent one-pot synthesis on a large scale.
