  Crystal structures, semiempirical PM3 calculations and NMR studies of trimesityllead bromide and dimesityllead dibromide

  摘要：

  Trimesityllead bromide has been synthesized by the reaction of mesityllithium with lead(II) chloride in tetrahydrofuran (THF). As a side product, dimesityllead dibromide was formed. The structures of both compounds were determined by single-crystal X-ray diffraction analysis. Both Mes PbBr and Mes,PbBr, were characterized by NMR (H-1, C-13 and Pb-207) and other spectroscopic methods. Pb-207-H-1 and Pb-207-C-13 coupling constants were determined. The experimentally obtained X-ray data were compared with those calculated at the semiempirical PM3 level. (C) 1999 Elsevier Science Ltd. All rights reserved.
