For the determination of absolute configuration of various chiral ketones, we examined some hydrazines having a heavy atom as crystalline auxiliaries, and found that 2-chloro-4,6-dinitrophenylhydrazine is a useful crystalline agent for carbonyl compounds. Chiral hydrazones prepared from the hydrazine and various chiral ketones gave suitable single crystals for X-ray crystallographic analysis. The absolute
为了确定各种手性酮的绝对构型,我们检查了一些具有重原子的肼作为结晶助剂,发现2-氯-4,6-二硝基苯肼是羰基化合物的有用结晶剂。由肼和各种手性酮制得的手性生成了合适的单晶,用于X射线晶体学分析。X的绝对构型是通过X射线晶体学分析使用氯原子的异常分散作用确定的。肼是用于确定各种手性酮的绝对构型的有用的结晶剂。
