摘要：

The reaction of tertiary silanes with the low valent palladium complex [(μ-dcpe)Pd]2 affords equilibrium mixtures with mononuclear silyl palladium hydrides. These complexes have been characterized by NMR spectroscopy and, in one case, by X-ray crystallography. The silyl palladium hydride complexes rapidly interchange silicon and hydride coordination environments in solution which give rise to extraordinary temperature-dependent kinetic isotope effects for the fluxional process. An intermediate 2η-Si-H complex is proposed for the interchange. Copyright © 2003 American Chemical Society.
