Hydrocinnamaldehyde is a reactive aldehyde that is used for the synthesis of other compounds. It can be obtained by catalyzing the oxidative cleavage of cinnamyl alcohol. Hydrocinnamaldehyde is also found in marine environments, where it reacts with oxygen to form an unstable compound called hydrocinnamic acid. Hydrocinnamic acid then undergoes an oxidation-reduction process that converts it to hydrocinnamaldehyde. Hydrocinnamaldehyde is one of two carbene precursors used in the Grubbs reaction, which allows for the selective formation of C-C bonds from alkenes and alkynes. The other carbene precursor, methyllithium, is commercially unavailable and has been replaced by hydrocinnamaldehyde as a more economical alternative in this reaction.
Hydrocinnamaldehyde can also be used to synthesize palytoxin, which is a toxic compound found in shellfish such as oysters and clams

2-Vinylnaphthalene is a chemical compound that belongs to the group of polymers. It is a colorless liquid with a boiling point of 260°C and a molecular weight of 192.19 g/mol. 2-Vinylnaphthalene has been shown to be highly resistant to radiation and can be used in polymer matrices as an electron-donor material. The polymerized form of 2-vinylnaphthalene has high resistance to photochemical degradation, and exhibits fluorescence properties with excitation at 350 nm.
2-Vinylnaphthalene has also been studied as a model system for the study of ionizing radiation, where it was found to exhibit high activation energies for decomposition reactions.
