Abstract
1-(Alkyl- or aryl-sulfinyl)naphthalenes activated by electron-withdraw ing substituents at the 2-position undergo substitution reactions on t reatment with Grignard reagents. Evidence suggesting that this transfo rmation proceeds through a ligand coupling reaction of sigma-sulfurane s is discussed. The ligand coupling reaction of homochiral sulfoxides with 1-naphthylmagnesium bromide furnishes atropisomeric 1,1'-binaphth yls in 60-95% e.e.
