Skeletal Reorganization of Mercaptoacetaldehyde Dialkyl Acetal in Acid: Formation of Disulphide, 1,2-Bis(mercapto)ethylene and 1,1,2-Tris(mercapto)ethane Derivatives
摘要:
AbstractThe reaction of mercaptoacetaldehyde dialkyl acetals 1a‐c in the presence of sulfuric acid, polyphosphoric acid and zinc chloride is described. Other than the disulfide reported previously, new compounds 1,2‐bis‐(mercapto)ethylene, 1,2,3‐tris‐(mercapto)ethane and 1,2‐bis‐(mercapto)methane have been isolated for the first time.
