Ein kontinuierliches Verfahren zur Darstellung von 2‐Chloräthansulfonylchlorid (CESC) durch photochemische Sulfochlorierung (SO, und C1, bei ‐30°C) von Äthylchlorid in Tetrachlorkohlenstoff wird beschrieben (Ausbeute 65%).

Infrared spectra of ethyl α-aminoacetates show three bands in the carbonyl region. Solvent effects show that this is not due to Fermi resonance. These spectra can be interpreted using a model that considers the interactions between the nitrogen lone pair and the carbonyl group. The existence of an equilibrium between the conformers caused by the different orientations of the nitrogen lone pair with respect to the carbonyl group can be forecast. This model enables the interpretation of the carbonyl absorptions of the α-substituted (methoxy and ethoxy) ethyl acetates.
