REFERENCES

• Can behave as a protected, highly-reactive cyanamide equivalent. Reacts with ketones in the presence of CsF, or KCN + 18-crown-6, to give N-cyanoimines. In the presence of TiCl₄, quinones give N,N'-dicyanoquinodiimines: Angew. Chem. Int. Ed., 23, 447 (1984); Liebigs Ann. Chem., 142 (1986). Molecules of this type have found use as acceptor molecules in charge transfer complexes: J. Org. Chem., 57, 5726 (1992).
