N2 - New air-stable tripodal triphosphine ligands 1,8,13-tris(diisopropylphosphino)-2,3-dimethoxytriptycene (P3T1) and 1,8,13-tris(diphenylphosphino)-2,3-dimethoxytriptycene (P3T2) are presented and discussed. Their synthesis is based on the first practical synthesis of 1,8,13-tribromotriptycene. Reaction with palladium leads to the formation of new pseudo-C3-symmetric carbometalated complexes: namely, Pd(P3T1)Cl and Pd(P3T2)Cl. The catalytic activity of the new ligands and complexes was tested in the palladium-catalyzed chemoselective transfer hydrogenation of α,β-unsaturated ketones.
