  Cyclometallated compounds. XIII. Cyclopalladation of 2-phenoxypyridine and structurally-related compounds

  摘要：

  2-Phenoxypyridine and 2-phenylsulfanylpyridine are cyclopalladated readily by palladium acetate to give six-membered metallocycles. Extension to the three isomeric bis(2-pyridyloxy)benzenes leads to a new series of doubly-cyclopalladated compounds. In contrast, 3-6-diphenoxypyridazine and 4-6-diphenoxypyrimidine only undergo monopalladation, whilst their sulfur analogues are resistant to cyclopalladation. All cyclometallated compounds are converted to their acetylacetonate derivatives and the X-ray crystal structure of one of these is described. (C) 1999 Elsevier Science S.A. All rights reserved.

  The aim of this study was to demonstrate the absolute necessity of control experiments for a correct interpretation of mercury drop test results when applied to mechanistic studies of palladacycle-catalyzed reactions. It was shown that the interaction of diverse azapalladacycles with metallic mercury leads to the formation of organomercuric chlorides during the redox-transmetalation process. The structure of these organomercurials was confirmed by elemental analysis, H-1, C-13H-1}, and Hg-199H-1} NMR spectra, X-ray diffraction analysis, and DFT calculations. The behavior and properties of C,N-mercuracycles bearing the weak and labile N center dot center dot center dot Hg bond are discussed on the basis of the temperature dependence of the NMR spectra and calculated thermodynamic parameters of the dechelation process.
