用合成法制备了[2’
6’-
3
H]除草醚和[2’
6’-
3
H]草枯醚。以间溴氯苯(Ⅰ)为起始原料
经催化卤-氚取代反应制得[3
5-
3
H]氯苯(Ⅱ);然后用硝酸-浓硫酸的混合物硝化(Ⅱ)得[3
5-
3
H]对氯硝基苯(Ⅲ);最后使(Ⅲ)分别与2
4-二氯苯酚或2
4
6-三氯苯酚起缩合反应生成[2’

H]除草醚(Ⅳ)和[2’
6’-

H]草枯醚(Ⅴ)
比活度分别为1.16TBq/mol和1.89TBq/mol
放化纯度均大于95%。
Preparation of [2’
6’- 3H] nitrofen and [2’
6’- 3H] chloronitrofen were described. [3
5- 3H] chlorobenzene (Ⅱ) was prepared by catalytic halogen- tritium exchange reaction from m- bromo- chlorobenzene (Ⅰ). Then (Ⅱ) was nitrated with a mixtrue of HNO3 and H2SO4 to give [3
5- 3H] P- chloronitrobenzene (Ⅲ). Finally (Ⅲ) was condensed with 2
4- dichlorophenol or 2
4
6- trichlorophenol to form [2’
6’- 3H] nitrofen(Ⅳ) and [2’
6’- 3H] chloronitrofen (Ⅴ). The specific activity of tritiated nitrofen and chloronitrofen was 1.16 and 1.89 TBq/mol respectively
both radiochemical purities were over 95%.
