Oxalyl halides

Star-Shaped Poly(ɛ-caprolactone)-co-poly(ethylene glycol) Synthesized with Oxalyl Chloride as Linker Molecule

“…This change suggests that other spectral contributions influence the shape of the mentioned band. It is known that the stretching band band of the O C Cl group appears around 975 to 938 cm −1 (20,21). Therefore, the spectral behavior suggests that acyl free groups of oxalyl chloride are included in the struture of PEG-PCL 8.…”

Vibronic spectra, ab initio calculations, and structures of conformationally non-rigid molecules of oxalyl halides in the ground and lowest excited electronic states. Part II: Theoretical investigation of oxalyl chloride

“…Early experimental investigations by X-ray diffraction [2] and vibrational spectroscopy [3][4][5][6][7][8] led to the conclusion that the trans-conformer of C 2h point symmetry (see Fig. 1) had the lowest energy.…”

Theoretical study on HO2‐initiated atmospheric oxidation of halogenated carbonyls

“…On the other hand, halogenated carbonyls such as oxalyl dibromide (BrC(O)C(O)Br) and oxalyl dichloride (ClC(O)C(O)Cl) are utilized widely as reagents in organic reactions, which have been characterized [43][44][45][46]. In the atmosphere, the sources [47,48] of oxalyl dibromide (BrC(O)C(O)Br) and oxalyl dichloride (ClC(O)C(O)Cl) are the OH-initiated oxidation of 1,2-dibromoethane and C 2 Cl 4 , respectively.…”
