Photochemical additions of aldehydes to quinones, quinone imines and quinone oximes
1968Klinger [1,2] found that 9,10-phenanthrenequinone reacted with aliphatic and aromatic saturated and unsaturated aldehydes e.g. acetaldehyde, benzaldehyde, and cinnamaldehyde under the influence of light. The photo-adducts 1 may be cleaved hydrolytically to give 9,10-phenanthrenediol and RCOOH; it is possible thus to convert aldehydes to the ...

Function of Quinones in Photosynthesis
1967Publisher Summary The quinones that are commonly found localized in chloroplasts are of three major types: the plastoquinones, tocopherylquinones, and vitamin K. In each of these groups, there is more than one type present. Plastoquinone A has a side chain with nine monounsaturated isopentenyl (isoprenoid) units.
