ABSTRACT
HgTeBu2t or C8H18TeHg. To obtain this compound, 11.8 mL of t-BuTeLi solution (~3.7 mmol) with stirring at −5°C was added to 3.65 mmol of t-butylmercuric chloride in 11 mL of tetrahydrofuran (Harris et al. 1987). After 10 min, the green-yellow solution was placed in a CCl4/dry ice slush bath (−23°C) and kept at this temperature while being concentrated to dryness under vacuum. The yellow residues were extracted for 3 min with 30 mL of toluene at −5°C and centrifuged, after which the solid was discarded. The yellow liquid was diluted with 15 mL pentane and left to crystallize at −78°C. The resultant yellow solid was washed twice with pentane at −78°C and dried under a stream of Ar for 7 h in the dark at 20°C. The mother liquor was concentrated to 5 mL under vacuum at −23°C, warmed to room temperature for less than 1 min to dissolve the solid, and diluted with 5 mL of pentane, and second crop of crystals was collected at −78°C. Recrystallization with toluenepentane or from neat pentane gave ne yellow prisms with irreproducible partial melting in the 80°C-90°C range and gradual darkening above 110°C. The reaction and all handling of this compound were carried out in dim light.
