COA of Formula: C6H5ClO3. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Methyl 5-chlorofuran-2-carboxylate, is researched, Molecular C6H5ClO3, CAS is 58235-81-7, about Infrared examination of rotational isomerism in alkyl furan-2-carboxylates: determination of thermodynamic parameters from infrared data. Author is Chadwick, Derek J.; Chambers, John; Macrae, Robert; Meakins, G. Denis; Snowden, Roger L..
Addnl. data considered in abstracting and indexing are available from a source cited in the original document. Solutions of 66 alkyl furan-2-carboxylates in CCl4 and MeCN were examined at high dispersion in the ir C:O region. In CCl4 one ester shows 4 bands, 8 show single bands, and 57 show well-separated doublets. With 1 exception, the doublets are due to rotational isomerism between syn-S-trans and anti-s-trans forms. The higher waveno. component of a doublet arises from the form with the higher dipole moment and higher enthalpy, probably the syn-s-trans rotamer. The failure of attempts to obtain reliable free energy and entropy differences reveals the shortcomings of standard approaches to the determination of energy differences between rotational isomers from ir data.
From this literature《Infrared examination of rotational isomerism in alkyl furan-2-carboxylates: determination of thermodynamic parameters from infrared data》,we know some information about this compound(58235-81-7)COA of Formula: C6H5ClO3, but this is not all information, there are many literatures related to this compound(58235-81-7).
