NMR Spectroscopic Studies on (exo, endo) C-2 Monosubstituted Norbornene Derivatives

open access: yesChinese Journal of Magnetic Resonance, 2021
The 1H NMR spectra of C-2 monosubstituted norbornene and its derivatives are usually difficult to assign due to the anisotropy effect of norbornene ring and being a mixture of exo- and endo- isomers. Based on the preparation of configurationally pure C-2

Insight into Solvent Coordination of an Iron Porphyrin Hydroxylamine Complex from Spectroscopy and DFT Calculations [PDF]

open access: yes, 2018
The reduction of Fe(OEP)(NO) in the presence of substituted phenols leads to a three‐electron reduction to form Fe(OEP)(NH2OH), which has been characterized by visible spectroscopy and electron stoichiometry.
