Diisobutylammonium bromide is found to be a unique improper ferroelastic in which the elastic degrees of freedom seem to play the essential role, giving rise to a domain pattern resembling that of martensitic phase transitions. A weak canted ferroelectricity turns out switchable by an electric field.

The reaction of β-bromopropiophenone with different amines in acetonitrile at 25 deg C was studied.It was found that in the case of primary and secondary amines, the end products of the reaction are β-aminopropiophenones, which form via the intermediate phenyl vinyl ketone.In the case of tertiary amines, the reaction ends at the stage of the formation of phenyl vinyl ketone.The reactivity of the amines in the formation of phenyl vinyl ketone is preferentially determined by their basicity.
