Dibromoisocyanuric acid bromination with

Dibromoisocyanuric acid sulfuric acid Bromination with dibromoisocyanuric acid... [Pg.409]

In 15% oleum, dibromoisocyanuric acid is a powerful brominating agent that bromi-nates nitrobenzene at 25 °C to pentabromonitrobenzene with 90% yield in one minute738. [Pg.576]

Methyl 4,5,6,7-tetrafiuorobenzo[h](hiophene-2-carboxylate is oxidized by trifluoroperacetic acid or m-CPBA to form a 2,3-epoxysulfbne reaction with chlorine or sulfuryl chloride produces a 2,3-dichIoride derivative <94JFCS1>. HOF MeCN is a novel oxidant which oxidizes a variety of thiophene derivatives to 3,5-dioxides <94CC1959>. Bromination of thieno[c]fused l,S-n hthyridines occurs with tetrabutylammonium perbromide <94H331> or with dibromoisocyanuric acid/sulfuric acid <94JHCS21>. [Pg.85]

Monobromination. 2,4-Dinitroluene allowed to react 0.5 hr. with 0.5 mole dibromoisocyanuric acid in coned. H2SO4 6-bromo-2,4-dinitrotoluene. Y 97%. — Dibromoisocyanuric acid is an excellent brominating agent for ar. compounds with strongly deactivating substituents. Side chain bromination does not occur. F. e. s. W. Gottardi, M. 99, 815 (1968) perbromination s. M. 100, 42 (1969). [Pg.409]
