Abstract
Chiral 1,2-bis[tris(dimethylamino)phosphinimino]cyclohexane (7a, 80% yield), 1,2-bis[tris(dimethylamino)phosphinimino]-1,2-diphenylethane (7b, 74% yield), 1,2-bis[triphenoxyphosphinimino]cyclohexane (9a, 85% yield), and 1,2-bis[triphenoxyphosphinimino]-1,2-diphenylethane (9b, 70% yield) have been prepared using (1R,2R)-1,2-diaminocyclohexane or (1R,2R)-1,2-diphenylethylenediamine and the corresponding phosphine dibromide derivatives (the Kirsanov route). 1,2-Bis[triphenylphosphinimino]cyclohexane (2), 1,2-bis[triphenylphosphinimino]-1,2-diphenylethane (3), and 1,2-diiminophosphoranes 7b and 9b reacted with [Pd(η3-C3H5)Cl]2 in the presence of a silver salt in CH2Cl2 at room temperature to afford the cationic complexes 10 (81% yield), 11 (84% yields), 15 (78% yield), and 16 (74% yield), respectively. According to the same general procedure, palladium complexes [(η3-PhCHCHCHPh)(2)Pd]TfO (13, 88% yield) and [(η3-PhCHCHCHPh)(3)Pd]TfO (14, 86% yield) have been prepared.
