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.

具有三脚架伪C 3-对称的三茂基配体的碳金属配合物
新型的空气稳定的三脚架三膦配体1,8,13-三（二异丙基膦基）-2,3-二甲氧基三蝶烯（P 3 T1）和1,8,13-三（二苯基膦基）-2,3-二甲氧基三蝶烯（P 3 T2）介绍和讨论。它们的合成是基于1,8,13-三溴三并茂的首次实用合成。与钯的反应导致新的伪C 3对称碳金属络合物的形成：即Pd（P 3 T1）Cl和Pd（P 3 T2）Cl。在钯催化的α，β-不饱和酮的化学选择性转移氢化中测试了新的配体和配合物的催化活性。
