Description

General description

1,2-Diaminopropane undergoes condensation with salicylaldehyde and its derivatives to form Schiff base. It reacts with formaldehyde and hydrogen peroxide in aqueous acidic solution to give cage peroxide, 1,6-diaza-3,4,8,9-tetraoxa-11-methylbicyclo[4.4.2]dodecane.

Application

1,2-Diaminopropane was used as model precursor in the electron induced deposition of amorphous carbon nitride films.
