En studie av konformationer och elektronövergångar i ett antal rodaniner, ett tiourinämne och ett par ditiokarbamater m.h.a. kristallografi, spectroskopi och datatekniska beräkningsmetoder.
Abstract
Analysis of conformations and electron transitions of 3-(alkyl or aralkyl)-5-(methyl or phenyl)rhodanines with analogues and N,N'-bis[(S)-1-phenylethyl]-thiourea have been performed by X-ray crystallography, 1H NMR, molecular mechanics, ultraviolet spectroscopy and for the chiral rhodanines, enantiomer chromatography and circular dichroism spectroscopy. The magnitude of rotational barriers has been determined. Attractive steric effect is determined in the syn form of 3-neopentyl-5-phenylrhodanine. Absolute configurations are determined for the anti and syn forms of 3-(S)-(1-phenylethyl)-5-methylrhodanine. A special study is made with the N-[(S)-(1-phenylethyl)]-dithiocarbamate anion and the equilibrium of its ammonium salt.
