One-pot synthesis of aryl butyl tellurides from tellurium tetrachloride and activated aromatics through a solventless step

Imine-functionalized, fluorescent organomercury and -tellurium compounds

“…ArTeCl 3 (Ar = C 6 H 5 , 4-Me-C 6 H 4 , 4-C 10 H 7 , 2,4,6-Me 3 -C 6 H 2 ) were prepared by the chlorination of their corresponding ditellurides [19][20][21]. However, 4-MeO-C 6 H 4 TeCl 3 was prepared from a direct reaction of TeCl 4 and anisole [22]. Fluorescence and electronic spectra were recorded on a Varian Luminescence Cary eclipsed and Perkin-Elmer-Lambda 20 UV-Vis spectrophotometer, respectively, by using a 10 mm quartz cell at room temperature.…”

New cation-dependent supramolecular arrangements of [RTeI4]− tectons: Synthesis and X-ray structural characterization of the mixed valence complex salts [p-CH3O(C6H4)Te(etu)][p-CH3O(C6H4)TeI4] (etu=ethylenethiourea) and [p-PhO(C6H4)Te(tu)][p-PhO(C6H4)TeI4] (tu=thiourea)

“…Methanol was dried with Mg/I 2 and distilled before use [10]. The respective ditellurides were prepared according literature procedures [11]. (2) To a red solution of 0.1186 g (0.2 mmol) of (pPhOC 6 H 4 Te) 2 -diphenoxyphenylditelluride -in 30 ml of methanol, 0.0506 g (0.2 mmol) of resublimed I 2 was added and the color turned black.…”

Reactive organometallics from organotellurides: application in organic synthesis

“…In one study the electrophilic substitution was performed in a solventless process 11 and in another one the hygroscopic tellurium tetrachloride was prepared and reacted in situ with the aromatic compound. 12 …”
