There is provided a brominating and oxidizing agent of the formula: STR1 wherein R1, R2, R3 and R4 which may be the same or different, represents a member selected from the group consisting of a hydrogen atom, a C1 -C22 straight or branched alkyl group, a phenyl group, and a substituted phenyl group whose substituents are selected from the group consisting of a methoxy group, a nitro group, a cyano group, a halogen atom (Br, Cl, I), a C1 -C2 dialkylamino group, a C1 -C2 dialkylaminomethyl group, a C1 -C2 dialkylaminoethyl group, a C1 -C2 dialkylammoniummethyl group, a C1 -C2 dialkylammoniumethyl group, a C1 -C2 trialkylammoniummethyl group, a C1 -C2 trialkylammoniumethyl group, a COOR5 group, and a CON(R5)2 group, wherein R5 represents a C1 -C8 straight or branched alkyl group. The compounds falling within formula (I) find wide application as brominating and oxidizing agents in a number of organic reactions in which the prior art compound, N-bromosuccinimide has been employed to date. In comparison to N-bromosuccinimide, the compounds of the instant invention are characterized as being extremely stable to degradation and less polar with respect to their N-Br bond than N-bromosuccinimide such that promotion of "radical" bromine release is achieved with minimal positive bromine release.
