title: Direct coupling of nitriles and aniline to form the triazapentadiene species [upper bond 1 start]Rh(III){NH=C(R)N(Ph)C(R=N[upper bond 1 end]H}.
abstract: The facile and high-yield reaction between aniline and cis-positioned nitriles of [((t)bpy)(2)Rh(NCR)(2)][OTf](3) [R = Me (2), Ph (3); (t)bpy = 4,4'-di-tert-butyl-2,2'-bipyridine; OTf = CF(3)SO(3)(-)] produces the Rh(III)-triazapentadiene species [((t)bpy)(2)[upper bond 1 start]Rh{NH=C(R)N(Ph)C(R=N[upper bond 1 end]H}][OTf](3) [R = Me (4), Ph (5)]. It represents the first example of direct coupling between two RCN ligands and a primary amine to form this type of metallacycle. X-ray structures of 2 and 4 are reported.
