    Notes: Deep Coloured Systems with Oxalic Acid Substructure-a Structural CorrectionBasing on a recent spectroscopic investigation the structure of earlier described deeply coloured systems derived from oxalic acid imidochlorides and thioacetamide has to be revised. Due to the poor solubility of these systems their spectroscopic characterization led to the misinterpretation as tetramethin-bridged thiazolines 1. By means of 1H-NOE-Difference-Spectroscopy of newly synthesized derivatives with lipophilic substituents a imidazolin-thion substructure 4 has been found. Such an arrangement of the heteroatoms clearly reflects a 1,3-rearrangement with participation of the oxalic acid system.
