摘要：
The synthesis of 1,2- bis( 5'- trihalomethylisoxazol- 3'- yl) ethanes ( 3- 6) and 1,2- bis( 5'trihalomethylpyrazol- 3'- yl) ethanes ( 7- 10) from the cyclocondensation of 1,1,1,10,10,10- hexahalo4,7- dimethoxydeca- 3,7- dien- 2,9- diones ( 1 and 2) with hydroxylamine and hydrazines is reported. In addition, the one- pot synthesis of 1,2- bis( 5'- alkoxycarbonylpyrazol- 3'- yl) ethanes ( 11- 14) by reaction of chloro- substituted dienone 2 and hydrazines is also described.
