He argued a non-classical cation was needed to explain the stability of the norbornyl cation.[1] This fueled a debate with Herbert C. Brown over the existence of σ-delocalized carbocations. Winstein also first proposed the concept of an intimate ion pair.[2] He was co-author of the Grunwald-Winstein equation, concerning solvolysis rates.[3]Richard F. Heck, who earlier in his career had undertaken postgraduate studies with Winstein, won the 2010 Nobel Prize in Chemistry.[4] References1. ^{{cite journal|last1=Young|first1=W. G.|last2=Cram|first2=D.
