A new and convenient method is described for the synthesis of hydrazonyl halides. Hydrazones on treatment with N-chlorosuccinimide-dimethyl sulfide complex result in the formation of the corresponding hydrazonyl chlorides in good yields. Similarly, treatment of hydrazones with N-bromosuccinimide-dimethyl sulfide complex gives the corresponding hydrazonyl bromide under extremely mild conditions.

A new family of isoxazolines has been obtained via 1,3-dipolar cycloaddition in good to high yields under mild conditions. Our approach focused on construction of the heterocyclic ring and direct access to a quaternary carbon center at position 5. The met
Synthesis of 3 H-1,2,4-Triazol-3-ones via NiCl2-Promoted Cascade Annulation of Hydrazonoyl Chlorides and Sodium Cyanate

A nickel-promoted cascade annulation reaction for the facile synthesis of 3H-1,2,4-triazol-3-ones from readily available hydrazonoyl chlorides and sodium cyanate has been developed. The transformation occurs through a cascade nickel-promoted intermolecular nucleophilic addition-elimination process, intramolecular nucleophilic addition, and a hydrogen-transfer sequence. The method has been successfully applied for the construction of the core skeleton of the angiotensin II antagonist.
Controlled polymerization of styrene in the presence of Blatter’s radicals
Burdyukova, T. O.,Fedorov, A. Yu.,Grishin, I. D.,Kuznetsova, Yu. L.,Lopatin, M. A.,Malysheva, Yu. B.,Polozov, E. Yu.,Vavilova, A. S.,Zaburdaeva, E. A.

Controlled polymerization of styrene (both self-initiated and initiated with azobisisobutyronitrile) in the presence of Blatter’s radical at 125 °C was studied. When using the radical initiator, there is no induction period. On the basis of UV spectroscopy and MALDI massspectrometry studies, it was established that the Blatter radical is completely consumed at the initial stage of the polymerization, inserting into almost all macromolecules. The prepared polystyrene exhibits the ability to reinitialization in post-polymerization and the synthesis of block copolymers.
