Direct irradiation of carbonyl compounds such as some aldehydes, ketones and anthraquinone in N,N-dimethylamiline(DMA), without using other solvents, gave $\beta$-hydroxyamines as the major products. Irradiation of anthrone and DMA in methanol afforded ${\gamma}$-hydroxyamine. The structure of the photoproduct was confirmed by treatment with an acid to give a bicyclic compound.

We confirmed that the 1 compound, N,N'-di(p-dimehylaniline)benza1d-1,4-diimine, with two imine bond showed a reversible trans-cis photoisomerization which was recovered to the original state in 8 minutes through the spectroscopic studies.
