Wamhoff, Heinrich,Bamberg, Christian,Herrmann, Stefan,Nieger, Martin
, p. 3985 - 3993 (2007/10/02)
The novel three-component reaction involving a heterocyclic iminophosphorane, an isocyanate, and a hetarene component is applied to an aromatic pyrazole iminophosphorane 1 and to an analogous pyrazolone derivative 13.The hitherto unknown zwitterionic pyra
