Abstract
Acetylenedicarbonyl fluoride and propiolyl fluoride were investigated in the Lewis acidic medium consisting of SbF5/CF3CH2F. The acetylenic acyl cations are characterized by vibrational spectroscopy, NMR spectroscopy, and single-crystal X-ray diffraction. The protonated species of propiolyl fluoride decomposes in a few hours at −78 °C in a dynamic vacuum which leads to the formation of the corresponding acylium cation. The room-temperature stable methylated acyl fluoride was prepared in the ternary system CH3F/SbF5/SO2. The experimental data are discussed together with quantum chemical calculations on the M06-2X/aug-cc-pVTZ level of theory.
期刊介绍：
The scope of ACS Earth and Space Chemistry includes the application of analytical, experimental and theoretical chemistry to investigate research questions relevant to the Earth and Space. The journal encompasses the highly interdisciplinary nature of research in this area, while emphasizing chemistry and chemical research tools as the unifying theme. The journal publishes broadly in the domains of high- and low-temperature geochemistry, atmospheric chemistry, marine chemistry, planetary chemistry, astrochemistry, and analytical geochemistry. ACS Earth and Space Chemistry publishes Articles, Letters, Reviews, and Features to provide flexible formats to readily communicate all aspects of research in these fields.
