A catalyst- and metal-free electrochemical hydrodehalogenation of aryl halides is disclosed. Our reaction by a flexible protocol is operated in an undivided cell equipped with an inexpensive graphite rod anode and cathode. Trialkylamines nBu3N/Et3N behave as effective reductants and hydrogen atom donors for this electrochemical reductive reaction. Various aryl and heteroaryl bromides worked effectively. The typically less reactive aryl chlorides and fluorides can also be smoothly converted. The utility of our method is demonstrated by detoxification of harmful pesticides and hydrodebromination of a dibrominated biphenyl (analogues of flame-retardants) in gram scale.

A novel copper(II)–salen complex was immobilized on the surface of magnetite nanoparticles using chitosan as a linker. This system exhibits superior catalytic activity in acetyl protection of various amines with thioacetic acid as the acetylating reagent. The method has advantages over others in high selectivity, simple work-up, green reaction medium and the application of an easily recoverable heterogeneous catalyst.

The N-alkylation of amides, lactams, carbamates, and N-heterocycles was easily attained in good yields by the electroreduction of the substrates in the presence of alkyl halides.

The kinetics of the noncatalytic and base-catalyzed aminolysis of benzoyl chloride (with pyridine as catalyst) and 2,4-dinitrophenyl acetate (with pyridine, ε-caprolactam and pyridine N-oxide as catalysts) by alkyl aromatic amines PhNHR were studied in benzene at 25 deg C.The obtained rate constants are described satisfactorily by the modified Taft equation, which takes account of the steric and inductive effects of the structure of the amine.The results are discussed in terms of base and nucleophilic mechanisms of catalysis.
