It is a pleasure to dedicate this short paper to Professor Henry Eyring, whose versatility and originality in several distinct fields of science are matched only by his gaiety of spirit and dedication to his work. It is not given to many people to write a textbook which should remain standard reading for more than twenty-five years and be completely described by the names of its authors. Yet so well-known is his Quantum Chemistry, written in collaboration with John Walter and George Kimball, that as soon as it was published in 1944 no one bothered about the title it was sufficient to refer simply to Eyring, Walter, and Kimball. ...

An explanation for the observed stereochemistry of addition was suggested in 1937 by George Kimball and Irving Roberts, who proposed that the reaction intermediate is not a carbocation but is instead a bromonium ion, R2Br" ", formed by electrophilic addition of Br" " to the alkene. (Similarly, a chloronium ion contains a positively charged, divalent chlorine, R2C1. ) The bromonium ion is formed in a single step by interaction of the alkene with Br2 and simultaneous loss of Br .

In 1937 chemists Irving Roberts and George Kimball suggested the observed trans-on y stereochemistry of this reaction could be explained by a three-member ring called a bromonium ion.
