Abstract
WITH reference to Dr. Morton's suggestion regarding the role of vitamin A aldehyde (axerophthal) in the chemical changes involved in photo-reception1, it may be of interest to mention that we prepared this substance some eighteen months ago by Oppenauer oxidation of vitamin A alcohol with aluminium isopropoxide in the presence of acetaldehyde. The ultra-violet absorption spectrum of the aldehyde showed maxima at 350 and 368 mμ in cyclohexane and a band at 657 mμ in the antimony trichloride reaction, and was characterized by the formation of a 2:4-dinitrophenylhydrazone, m.p. 207–209°.
