An infrared study of the reaction of acetylene halides: HCCCl with O2

The reaction of HCCCl with O₂ has been investigated by using the FTIR/matrix isolation technique. The twin-jet codeposition and merged single jet deposition at short sample distances, in either the gas phase or an Ar matrix, gave no apparent new band. Many new peaks were observed as the merged length increased to 19 cm. From the position of the new absorptions, CO, CO₂, and formyl chloride (HCOCl) are observed as major products. Glyxoal chloride (HCOCOCl) is tentatively assigned as an intermediate and is isolated for the first time in this study. The possible reaction mechanism is also discussed.
