22.1.1.1.4.4 Method 4: Reaction of C—H Acidic Compounds with Sulfonium Salts Bearing a ­Leaving Group

DOI: 10.1055/sos-SD-022-00003

Aggarwal, V. K.; Richardson, J.; Winn, C. L.Science of Synthesis, (20052235.

Sulfonium salts can, in certain cases, be transformed into ylides by a ligand exchange process (Scheme 44). Hence, a sulfonium salt bearing a leaving group (such as 68) can be converted into a sulfonium ylide by a nucleophilic carbanion {for further information, see Science of Synthesis, Vol. 27 [Heteroatom Analogues of Aldehydes and Ketones (Section 27.1.3.1.327.1.3.1.3)]}.[‌114‌]
