实验步骤: 18 g of 2,6-dimethylphenyl-hydrazine and 14 g of triethylamine were dissolved in 150 ml of ethyl ether. Keeping the temperature at 0° C., 12.5 g of methyl chloroformate were added dropwise to the solution. Precipitation of the chlorohydrate of triethylamine was observed. at 0° C.

实验步骤: To a mixture of 127 g (0.935 mol) 2,6-dimethylphenylhydrazine, 102.5 g (1.3 mol) pyridine and 400 ml water is added, at 0°-5°, 133.5 g (0.935 mol) chloroformic acid β-chloroethyl ester. After the addition is complete, the mixture is stirred for 2 hours at room temperature, the formed precipitate filtered off, washed with water and dried. The so obtained title compound is recrystallised from toluene to yield colourless crystals, m.p. 74°-75°. is added, at 0°-5° After the addition the formed precipitate filtered off washed with water dried

实验步骤: 2,6-Dimethylphenylhydrazine (68 mg, 0.50 mmol) was reacted with bis-(p-methoxyphenyl)-telluroxide for 0.2 h. to yield m-xylene (70%, p.l.c. (benzene-petroleum ether 1:1) afforded bis-(p-methoxyphenyl)-telluride (126 mg, 74%) and what appears to be 2,6-dimethylphenyl-4-methoxyphenyl-telluride as a colourless oil, m/e 342 (M+, 100%), 234, 212, 197, 105, 104, 79, 77, and 77.
