Abstract

The solvent and concentration dependence of the isomeric equilibria of 1‐methylamino‐2‐niroethene were studied by ^1^H and ^13^C NMR spectroscopy. The results are used for clarification of the controversy regarding the content of the E form in CDCI~3~ solution, correcting an earlier suggestion concerning the stereochemical assignments around the C‐1N bond in the E form and verification of the values of the olefinic one bond proton—carbon spin—spin coupling constants, ^1^J(C,H), reported recently. An unambiguous means of assigning the stereochemistry around the C‐1N bond in the E isomer is suggested, based on using the complementary information from ^3^J(C‐2,NH) and ^3^J(H‐1,NH), in addition to the ^3^J(Me,H‐1) vicinal coupling constant.

In the title compound, C 17 H 21 NO 2 , there are two chiral C atoms. There are two intramolecular hydrogen bonds and one intermolecular hydrogen bond. The latter intermolecular hydrogen bond links the molecules in a helical fashion along the b-axis direction.
