Saul Winstein (October 8, 1912 – November 23, 1969) was a Canadian-American^[1] chemist who discovered theWinstein reaction. He argued anon-classical cation was needed to explain the stability of the norbornyl cation.^[2] This fueled a debate withHerbert C. Brown over the existence of σ-delocalized carbocations. Winstein also first proposed the concept of anintimate ion pair.^[3] He was co-author of theGrunwald–Winstein equation, concerning solvolysis rates.^[4]

Richard F. Heck, who earlier in his career had undertaken postgraduate studies with Winstein, won the 2010Nobel Prize in Chemistry.^[5]
