We describe the synthesis of a triazolyl-pyridine-based aminophosphine, N-(diphenylphosphaneyl)-6-(1-phenyl)-1H-(1,2,3-triazol-4-yl)pyridine-2-amine [2,6-{(PPh2)-N(H)(C5H3N)(C2HN3C6H5)}] [1, PN(H)N hereafter], and its palladium platinum complexes their catalytic application. The reaction 1 with [M(COD)Cl2] (M = Pd or Pt) afforded cationic complex [(MCl){PN(H)N}-κ3-P,N,N]Cl [M (2) Pt (3)]. Alternatively, compounds 2 3 were also synthesized by treating [2,6-{H2N(C5H3N)(C2HN3C6H5)}] (A) Pt), followed addition stoichiometric amounts PPh2Cl Et3N. neutral, dearomatized [(MCl){PNN}-κ3-P,N,N] (4) (5)] prepared deprotonation NH equiv tBuOK. Compounds 4 5 stepwise to give intermediate [{MCl2}2,6-{NH2(C5H3N)(C2HN3C6H5)-κ2-N,N}] (B) (C)], which subsequently phosphinated. in situ-generated PNN ligand-stabilized nanoparticles from compound catalyzed annulation o-bromobenzaldehyde alkynes yield indenone derivatives.
