Abstract
13C chemical shifts of diethyl alkyl-substituted malonates and their sodium salts in dimethylsulfoxide are reported. The resonances of carbonyl carbons and α-carbons having an active hydrogen in the sodium salts were respectively found at 0.5∼1 ppm 20 ppm lower fields than those of the original malonates did.
