13C‐NMR‐spektroskopische Analyse von Gemischen Isomerer Alkyl‐4‐butylmorpholine

13 C‐N.M.R. Spectroscopical Analysis of Mixtures of Isomeric Alkyl‐4‐butylmorpholines Mixtures of isomeric alkyl‐4‐butylmorpholines 3 were prepared by the treatment of several 2,2′‐dichloroalkyl ethers 1 (from the chlorination of alk‐1‐enes in the presence of ethylene oxide or propylene oxide) with butylamine and distinguished by 13 C‐n.m.r. The distribution of isomers of 3 is not changed in relation to that of 1 except 3g,g′ .
