Abstract

Bis(aryltelluro)ethynes ArTeC≡CTeAr (Ar≡C6H5 (1), p-MeC6H4 (2), p-Me2NC6H4 (3), p-FC6H4 (4), p-ClC6H4 (5), p-BrC6H4 (6), p-IC6H4 (7), p-PhC6H4 (8), p-PhOC6H4 (9), α-C10H7 (10), β-C10H7 (11)) were prepared in 42-97% yields, by reacting BrMgC≡CMgBr with two equivalents of the corresponding ArTeX formed in situ. These organotellurium compounds were characterized by 1H- and 13C-NMR and IR spectroscopies. The X-ray crystal structures of 1, 2, 3, 7 and 9 were determined, and showed that the TeC≡CTe moieties are ca. linear, while the coordination at the Te atoms is angular. The ranges of some geometric parameters are: Te-C(sp2), 2.103(5)-2.142(6) Å; Te-C(sp), 2.021(6)-2.058(6) Å; C≡C, 1.166(12)-1.203(11) Å; C-Te-C, 94.2(3)-97.2(2)°. © 2002 Elsevier Science B.V.
