Chapman, Norman Bellamy; Ewing, David F.; Scrowston, R. M.; Westwood, R. published an article in 1968, the title of the article was Proton magnetic resonance spectra of some benzo[b]thiophene derivatives.Formula: C9H5ClOS And the article contains the following content:
Attempts are made to correlate the chem. shifts in the 100 Mc./sec. 1H N.M.R. spectra of 42 benzo[b]thiophene derivatives with the substituents present in the mol., and the relations are rationalized where possible. Coupling constants are also recorded, and their dependence on bond order and on other factors is discussed. The changes in the chem. shifts and coupling constants when the benzo[b]thiophenes are oxidized to the 1,1-dioxides are recorded and discussed. 43 references. The experimental process involved the reaction of 5-Chlorobenzo[b]thiophene-3-carbaldehyde(cas: 16296-68-7).Formula: C9H5ClOS
The Article related to thiophenes nmr benzo, benzothiophenes nmr, nmr benzothiophenes, nmr (nuclear magnetic resonance) and other aspects.Formula: C9H5ClOS
