Alkenylation of arylamines and N-arylacetamides with acetylene compounds in superacids
摘要:
Vinyl type cations generated in superacid HSO3F by the protonation of the triple bond of acetylene compounds efficiently react with arylammonium ions and N-arylacetamides yielding alkenylation products of the aromatic rings in the given amino derivatives. The regio- and stereoselectivity of electrophilic aromatic substitution was investigated involving vinyl type cations and arylammonium ions or N-arylacetamides in HSO3F.
