Carbon-13 NMR Spectra of Methylated Cyclobutanes and Ethyl Cyclobutanecarboxylates
The 13C NMR spectra of cyclobutane and seven methylated homologs and of ethyl cyclobutanecarboxylate and five isomeric diethyl cyclobutanedicarboxylates are reported and substituent parameters for methyl groups in methylcyclobutanes are calculated.Of note is a sizeable and nearly configuration-independent upfield shifting γ-effect.
