27.1.3.1.1 Method 1: By Deprotonation of Sulfonium Salts

DOI: 10.1055/sos-SD-027-00002

Aggarwal, V.; Richardson, J.Science of Synthesis, (20042759.

As conjugate bases of the corresponding sulfonium salts, the most commonly employed method for the synthesis of sulfonium ylides 99 is deprotonation (Scheme 52). The popularity of deprotonation as a method for the generation of sulfonium ylides can be ascribed to the ease with which sulfonium salts can be prepared. The experimental conditions used for deprotonation vary widely according to the intended use, stability of the ylide, and the pKa of the sulfonium salt.
