Abstract
The synthesis and crystal structure of (E)-3-((S)-1-phenylethylamine)methylene R-(+) camphor are discussed. The 1H NMR spectrum in a chloroform solution indicates the existence of a mixture of two tautomers, the main tautomer corresponds to the E-isomer. On the other hand, in the solid state, the crystal structure solved by X-ray diffraction shows only the occurrence of this latter form. Crystal data: monoclinic (P21), a = 11.019(4) Å, b = 6.782(2) Å, c = 11.186(4) Å, β = 101.843(4)°.
