Thiophene S,N-ylides readily react with electron-rich dienophiles yielding adducts formed by the efficient extrusion of acyl- and sulphonyl-thionitroso-compounds, themselves readily trapped by Diels-Alder or ene reactions; similar but slower cycloadditions occur with the analogous S,C-ylides, a potential source of thiocarbonyl derivatives.
