Reactivity Profile

ENDRIN ALDEHYDE is a chlorinated aldehyde derivative. Aldehydes are frequently involved in self-condensation or polymerization reactions. These reactions are exothermic; they are often catalyzed by acid. Aldehydes are readily oxidized to give carboxylic acids. Flammable and/or toxic gases are generated by the combination of aldehydes with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents. Aldehydes can react with air to give first peroxo acids, and ultimately carboxylic acids. These autoxidation reactions are activated by light, catalyzed by salts of transition metals, and are autocatalytic (catalyzed by the products of the reaction). The addition of stabilizers (antioxidants) to shipments of aldehydes retards autoxidation.

Health Hazard

Inhalation of material may be harmful. Contact may cause burns to skin and eyes. Inhalation of Asbestos dust may have a damaging effect on the lungs. Fire may produce irritating, corrosive and/or toxic gases. Some liquids produce vapors that may cause dizziness or suffocation. Runoff from fire control may cause pollution.

Fire Hazard

Some may burn but none ignite readily. Containers may explode when heated. Some may be transported hot.

An Unexpected Intramolecular Photoreaction of a Hexachlorooctahydrodimethanonaphthaline

Photoreactions of 1,2,3,4,10,10-hexachloro-6,7-epoxy-1,4,4a,5,6,7,8,8a-octahydro-1,4-endo,endo-5,8-dimethano-naphthaline (1) were studied in acetone with wavelengths above 290 nm.With the help of column chromatography an unusual isomerisation product (4) could be isolated, whose structure was established by spectral data obtained by mass spectrometry infrared spectroscopy, 1H and 13C nuclear magnetic resonance measurements. - Keywords: Photochemistry, Isomerisation Reactions, Hexachlorooctahydrodimethanonaphthalines
