[求助] 求助英文文献翻译

A mixture containing phenyl hydrazine or hydrazine
(5 mmol) and 1 (5 mmol) was sonicated in a 10 mL test
tube for appropriate length of time (as indicated in Table
1) until TLC showed complete disappearance of the start-
ing materials. In temperature controlled experiments, reac-
tions were performed in a water bath at 25 ± 1 C. The
reaction mixture was poured into ice–water mixture and
the precipitates were collected by ?ltration. The pure prod-
uct was obtained by recrystallization of the precipitates
using ethanol and water. Products were identi?ed based
on their melting point,H NMR,C NMR, and IR data.
Known structures were veri?ed by comparison of their
data with those reported in the literature [26].

简单
将5mmol的水合肼或者苯肼与1mmol 1的混合物放入10ml试管中超声适当的时间（在表1中描述的），直到TLC监测原料完全消失。实验过程中水浴的温度控制在 25 ± 1 C。反应完全后将反应液倒入冰水中，过滤并收集析出的沉淀物，经过乙醇和水混合溶剂重结晶得到纯的产品，产品通过熔点测定、H NMR,C NMR, and IR 确认。通过对比文献【26】中报道的数据确认了这种已知产品的结构。
