Methylvinyl telluride

Preparation of alkylvinyl tellurides by reaction of Te/KOH/alkyl iodides, SnCf in HMPA/H2O with pressurized acetylene. Methylvinyl telluride. 12.8 g of Te, 1.42 g of methyl iodide, 48.7 g KOH, 24.7 g SnCl2, 80 mL HMPA and 70 mL HjO were heated (105-115°C) in a rotating autoclave 1 L under acetylenic pressure (initial pressure 14 atm, residual pressure 7 atm, absorbed acetylene 0.8 mol) tor 5 h. The reaction mixture is evacuated at 1 mmHg. The fraction (10.5 g) collected into a cooled trap (-70°C) contains, according to GLC data, methylvinyl telluride (0.34 g, yield 20%), divinyl telluride (10 g, yield 55%) and dimethyl telluride (0.12 g, yield 8%) b.p. 115-116°C.
