Abstract

The palladium- and copper-catalyzed cross-coupling of diaryl- or divinyl tellurium dichlorides with organostannanes has been achieved in the presence of PdCl2 (10 mol%) or CuI (10 mol%) with Cs2CO3 (2 equiv.) in MeCN in good to moderate yields; alternatively, the palladium- and copper-catalyzed carbonylative cross-coupling of organotellurium dichlorides with organostannanes was readily accomplished under atmospheric pressure of CO in good to moderate yields.

Diphenyltellurium dichloride (1a): TeCl4(40 mmol) and PhHgCl (80 mmol) were heated under reflux in anhydrous dioxane (100 ml) for 2 h. The solution is cooled to 10 °C and the HgCl2 dioxane precipitate filtered off and washed with cold dioxane (15 ml). The filtrate was poured with stirring into 1% ice-cold HCl (400 ml). The dichlorides precipitate as crystalline solids and were recrystallized from benzene–light petroleum (bp 30–60 °C. Di[β-(Z)-styryl]tellurium dichloride (1c): NaBH4(9 mmol) was added in small portions to a stirred suspension of Te (3 mmol) in EtOH (15 ml), and THF (5 ml) was added to the hot mixture, which was then refluxed. After 15 min the mixture turned dark violet and the reflux was continued until all the Te had disappeared. The heat source was removed and the phenylacetylene (7.8 mmol) added. When the color changed to yellow, the mixture was cooled at room temperature, diluted with EtOAc (50 ml) and washed first with saturated aqueous NH4Cl (3 × 30 ml) and then with brine (3 × 30 ml). The organic phase was separated, dried (MgSO4) and evaporated in a rotary evaporator. The residue dissolved in a small amount of CHCl3 was treated dropwise, while cooling (ice bath) and stirring, with a solution of an equimolar amount of SO2Cl2 in the same solvent. By addition of a large excess of light petroleum (bp 30–60 °C) the dihalide precipitates as a crystalline solid Search PubMed.
