Application of N-methylpyrrolidin-2-one hydrotribromide in organic synthesis

The review describes the broad applicability of a modern reagent, N-methylpyrrolidin-2-one hydrotribromide (MPHT), in organic synthesis. The methods for its preparation and use in the bromination reactions of different classes of organic compounds (alkenes, alcohols, ketones, etc.), in the oxidation and epoxide ring-opening reactions, in conversions of alkenes to aziridines are considered. Special attention is given to the environmentally friendly character of MPHT.
