  摘要：

  Ph2SiCl2 and PhMeSiCl2 react with Li2E (E = S, Se, Te) under formation of trimeric diorganosilicon chalcogenides (PhRSiE)(3) (R = Ph: 1a-3a, R = Me: cis/trans-4a (E = S), cis/trans-5a (E = Se)). In case of E = S. Se dimeric four-membered ring compounds (PhRSiE)(2) (R = Ph: 1b-2b, R = Me: cis/trans-4b (E = S), cis/trans-5b (E = Se)) have been observed as by-products. 1a-5b have been characterized by multinuclear NMR spectroscopy. (H-1, C-13, Si-29, Se-77, Te-125). Four- and six-membered ring compounds differ significantly in Si-29 and Se-77 chemical shifts as well as in the value of (1)J(SiSe).The molecular structures of 2a, 3a and trans-5a reported in this paper are the first examples of compounds with unfused six-membered rings Si3E3 (E = Se, Te). The Si3E3 rings adopt twisted boat conformations. The crystal structure of 3a reveals an intermolecular Te-Te contact of 3.858 A which yields a dimerization in the solid state. (C) 2004 Elsevier B.V.
