Variable-temperature proton n.m.r. spectroscopy has been used to study the inversion barriers and conformations of 3.4-dialkyltetrahydro-1.3.4-oxadiazines. The predominant conformer of 3,4-dimethyltetrahydro-1.3,4-oxadiazine was found to be 3ax, 4eq.
可变温度质子核磁共振光谱已被用于研究3.4-二烷基四氢-1.3.4-恶二嗪的转化障碍和构象。发现3,4-二甲基四氢-1.3,4-恶二嗪的主要构象异构体为3 ax,4 eq。
