摘要：

The IndH(2)(CH2Py)(2) 1-H pro-ligand has been prepared and its coordination to Pd(II) has been investigated. Mono-lithiation of 1-H gives a symmetric piano-stool complex 2 in which the indenyl ring is 715-coordinated and the two pyridine sidearms are bonded to lithium. Treatment of 2 with [Pd(PhCN)(2)Cl-2] and direct reaction of 1-H with Na2PdCl4 lead to the same unsymmetric Pd pincer complex 3, whose structure was ascertained by NMR spectroscopy and X-ray diffraction. The formation of this NCsp3N Pd pincer complex results from the rearrangement of a 2-indenylbispyridine pincer complex via H shift from one of the CH2 linker to the central carbon atom of the indenyl backbone linked to Pd (C2).
