The preparation and isolation of the first palladium dihydrogen complex is described. NMR spectroscopy reveals a very short HH bond length, but the hydrogen molecule is activated toward heterolytic cleavage. An X‐ray crystal structure suggests that proton transfer to the t Bu PCP ( κ 3 ‐2,6‐( t Bu 2 PCH 2 ) 2 C 6 H 3 ) pincer ligand is possible. The basicity of the ipso ‐carbon atom of the pincer ligand was investigated in a related complex.
