aliphatic oximes (1–4) the influence of the oximesubstituent on the 13C NMR chemical shifts has been studied. Various 2D NMR techniques were applied for the unequivocal assignment of their 1H and 13C resonances. For bicyclohexylidene oximes 1–2 long-range substituenteffects on the 13C NMR chemical shifts of aliphatic carbon atoms of the six-membered rings due to the presence of the oxime group are
对于一系列棒状脂肪族肟(1-4),已经研究了肟取代基对13 C NMR化学位移的影响。将各种2D NMR技术应用于其1 H和13 C共振的明确分配。对于双环己基肟,由于存在肟基,在六元环的脂肪族碳原子的13 C NMR化学位移上有1–2个远程取代基作用,直至远离亚氨基的6个碳碳键为止碳!在13从双环己基肟3-4获得的C NMR数据表明,在该系列反应中,作用仅限于与亚胺基碳有5个键的碳原子。观察到的两个系列之间的差异归因于存在于1-2中的烯烃双键,该双键被肟取代基的电场极化。
