Abstract

Croconic acid is the first organic ferroelectric molecule to experience high polarization at room temperature. In this experiment, we want to observe the ferroelectric effects of substituting a functional group on croconic acid. Croconic acid has five different reaction sites, leaving it susceptible from multiple additions of the desired substrate, being hydroxylamine. Our approach is to substitute a carbonyl with a hydroxylamine. Due to croconic acids symmetry, methyl protecting groups must be added to force a single addition of hydroxylamine. The methylation of disilver croconate was successful there by yielding dimethyl croconate.
