First example of an imine addition to coordinated isonitrile

The interplay between cis-[PtCl2{CNC6H3(2,6-Me2)}2] and Ph2Cdouble bond; length as m-dashNH results in the addition of benzophenone imine to one isonitrile ligand to yield the aminoimino-carbene cis-[PtCl2{CNC6H3(2,6-Me2)}{C(Ndouble bond; length as m-dashCPh2)N(H)C6H3(2,6-Me2)}]. The formulation of the latter compound is based on the coherent 1H and 13C{1H} NMR and ESI-MS data. This adduct is not stable in solution even at room temperature leading to diamino-carbene cis-[PtCl2{CNC6H3(2,6-Me2)}{C(NH2)N(H)C6H3(2,6-Me2)}], which is, formally, the product of the addition of ammonia to one isonitrile ligand in cis-[PtCl2{CNC6H3(2,6-Me2)}2].
