Abstract

2-Aryl-1-chloro-1-fluoroethyl sulfoxides underwent nucleophilic desulfinylation with PhMgBr to give (Z)-fluorostyrene derivatives in a very stereoselective manner (> 33: 1) via an α- fluorocarbene species. When treated with 3 equiv of PhLi in the presence of N, N, N′, N′- tetramethylethylenediamine, they similarly formed fluorostyrenes as a stereoisomeric mixture (E: Z= 2: 1), but with 1 equiv of PhLi 2-aryl-1-chloro-1-fluoroethanes were the ...
