Reactions of 2H-azaphosphirene complex 1 with electron-rich nitrile derivatives 2a-e in the presence of substoichiometric amounts of ferrocenium hexafluorophosphate yielded regioselectively 2H-1,4,2-diazaphosphole complexes 3a-e under mild conditions. The dependence of the reaction on the amount of ferrocenium hexafluorophosphate is discussed. In the reactions of 1 with electron-poor nitrile derivatives HCN (2f), EtOC(O)CN (2g), and C 6F5CN (2h), byproducts possessing a P-F bond are formed, which indicates that the hexafluorophosphate anion is involved in the reaction course. Apart from NMR spectroscopic (3a-f) and X-ray data (3b, 3d-e), a detailed DFT study is included that provides first insight into the reaction pathway. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.
