A convenient synthesis of N-aryltrifluoroacetimidoyl phthalimide and succinimide

N-aryltrifluoroacetimidoyl chlorides have been prepared in a one-pot stage and allowed to react with nitrogen nucleophiles. In these reactions chlorine acts as an element replaceable with nitrogen to produce trifluoroacetimidoyl phthalimide and trifluoroacetimidoyl succinimide in good to excellent yields.
