That Fascinating Nonclassical Ion Problem

  • Herbert C. Brown


In science it is rare that a concept, once it has been fully accepted and incorporated into both current theory and textbooks, is successfully challenged. For fifteen years the author and his students have been engaged in a research program directed to testing the validity of the proposal that σ-bridges play a major role in the structures and chemistry of the 2-norbornyl1 and the cyclopropylcarbinyl2 cations, as well as numerous other σ-bridged, so-called “nonclassical ions.”3
