Synthesis and reactivity of a 1-Aza-2,3-diphosphaallyl anion

Article abstract of DOI:10.1021/om00047a006

The 1-aza-2,3-diphosphaallyl system [Mes *PPNMes*]Li (2; Mes* = 2,4,6-t-Bu₃C₆H₂) was obtained from the corresponding aminodiphosphene 1 by abstraction of the amine proton by n-BuLi. Reaction of 2 with nickelocene affords the metalloiminophosphane complex 3, the structure of which was determined by X-ray crystallography.
