13 C FT NMR spectra of ethyl cis ‐2‐substituted cyclopropanecarboxylates were obtained in chloroform‐ d and the chemical shifts were compared with those of the corresponding trans isomers. In most cases, the resonances for the ring carbons and the carbonyl group carbon appeared further upfield than those of the trans isomers, and were found to be useful for distinguishing the stereoisomeric 1,2‐disubstituted cyclopropanes.
