摘要

A series of mesylate derivatives of a-hydroxy thiophosphonates, RCH (OMs) PS (OEt),(8), have been prepared. These mesylates can react by k, processes under solvolytic conditions if cation stabilizing groups such as p-anisyl or p-thioanisyl groups are present. However, under conditions of appropriate electron demand, mesylates 8 can react by k,, processes involving thiophosphoryl participation. The cyclic intermediate ions capture acetic acid at ...
