Organyltellurium trichlorides

Sections 3.1-3.3 outline the principal preparative methods of diorganyl tellurides and ditellurides, organyltellurium trichlorides and diorganyltellurium dichlorides, which were the first classes of compounds investigated at the beginning of tellurium organic chemistry. [Pg.9]

Organyltellurium trichlorides and diorganyltellurium dichlorides are prepared starting from the electrophilic tellurium tetrachloride (or arylteUurium trichlorides) by ... [Pg.11]

Organyltellurium trichlorides and the not directly accessible tribromides and triiodides are obtained by the halogenolysis of the Te-Te bond of the corresponding ditellurides. [Pg.11]

The reaction of organyltellurium trichlorides with NaBH followed by the in situ treatment of the generated tellurolate with alkyl halides is a useful method to prepare several types of unsymmetrical telluride ... [Pg.29]

Vinylic and cyclic organyltellurium trichlorides undergo similar reactions. [Pg.29]

The reduction of organyltellurium trichlorides, which are the primary products of several reactions involving tellurium tetrachloride (see Section 3.5.1), is a useful and general method for the preparation of diorganyl ditellurides. [Pg.42]

Organyltellurium trichlorides, tribromides and triiodides are well-known compounds, the trichlorides being the most familiar and useful for synthetic purposes. [Pg.47]

Organyltellurium trichlorides from tellurium tetrachloride and organic substrates... [Pg.47]

Organyltellurium trichlorides (general procedure) A solution of the ditelluride in benzene or CCI4 is treated dropwise at 0°C with a slight excess of SO2CI2 in the same solvent. The crude precipitate of the trichloride is separated by filtration. The yield is close to 100%. [Pg.51]

Additional method preparation of organyltellurium trichlorides and tribromides by the reaction of tetraorganyltin compounds with tellurium tetrachloride and tetrabromide ... [Pg.52]

Employing appropriate ratios of reagents and experimental conditions, some of the reactions that convert tellurium tetrachloride into organyltellurium trichlorides (see Section 3.5.1) can be applied to the synthesis of diorganyltellurium dichlorides. [Pg.57]
