Synthesis of β-chloro(trifluoromethyl)acroleins and a specific reaction towards β-aminothiols
β-chloro-β-(trifluoromethyl)acroleins and β-chloro-α-(trifluoromethyl)-acrolein have been synthesized through Vilsmeier's reaction. A specific 1,4-addition of the nitrogen atom from β-aminothiols is observed.
