prepared, in which a polar methylene group is allowed on steric grounds to interact intramolecularly with a nearby donor atom. The i.r. and 1H n.m.r. spectra of these sulphones are compared with spectra of reference compounds in which no such interaction is possible. No conclusive evidence for intramolecularhydrogenbonds is found: possible causes for the observed spectral shifts are discussed.
已经制备了分别包含氰基甲基磺酰基和苄基磺酰基的两个系列的砜,其中在空间上允许极性的亚甲基与附近的供体原子分子内相互作用。将这些砜的ir和1 H nmr光谱与参考化合物的光谱进行了比较,在参考光谱中不可能发生这种相互作用。找不到分子内氢键的确凿证据:讨论了观察到的光谱位移的可能原因。
