WebArsenic tribromide is the inorganic compound with the formula As Br 3.This pyramidal molecule is the only known binary arsenic bromide. AsBr 3 is noteworthy for its very high refractive index of approximately 2.3. It also has a very high diamagnetic susceptibility. The compound exists as colourless deliquescent crystals that fume in moist air. WebHypervalent halogen compounds, in particular iodine compounds, are very efficient and selective oxidants which tolerate a wide range of functional groups. The electrophilic …

WebThe use of the hypervalent iodine reagents in oxidative processes has become a staple in modern organic synthesis. Frequently, the reactivity of λ 3 iodanes is further enhanced by acids (Lewis or Brønsted). The origin of such activation, however, has remained elusive. WebApr 24, 2024 · It is demonstrated that the intrinsic reactivity of the bench-stable bromine(III) species can be unlocked by addition of a Lewis or a Brønsted acid. Abstract In sharp contrast to hypervalent iodine(III) compounds, the isoelectronic bromine(III) counterparts have been little studied to date. small holiday staff party email
