Saul Winstein (October 8, 1912 – November 23, 1969) was the Canadian chemist who discovered the Winstein reaction, in which he argued a non-classical cation was needed to explain the stability of the norbornyl cation. This fueled a debate with Herbert C. Brown over the existence of delocalized cations such as this.

Richard F. Heck, who earlier in his career had undertaken postgraduate studies with Winstein, won the 2010 Nobel Prize in Chemistry.[1]

Co-author of the Grunwald-Winstein equation concerning solvolysis rates.[2]
