摘要：

Phosphorus mononitride (PN) and arsenic mononitride (AsN) species supported by two different N-heterocyclic carbenes were prepared: The reaction of [(IDipp)NSiMe3] [IDipp = 1,3-bis(2,6-diisopropylphenyl)imidazolin-2-ylidene] with PCl(3)or AsCl(3)afforded the dichlorides [(IDipp)NECl2] (E = P, As) and, after the addition of IMes [IMes = 1,3-bis(2,4,6-trimethylphenyl)imidazolin-2-ylidene], the cationic chloro species [(IDipp)NE(Cl)(IMes)]Cl (E = P, As), which were reduced with potassium graphite (KC8) to yield the neutral compounds [(IMes)PN(IDipp)] and [(IMes)AsN(IDipp)], which exhibit the typicaltrans-bent geometry of dicarbene-dielement species in the solid state according to single-crystal X-ray diffraction.
