SUBSTITUENT EFFECTS ON THE PHOTOCHEMISTRY OF o-TOLUALDEHYDES

Charlton, James L.,Koh, Kevin

, p. 5595 - 5598 (2007/10/02)

The effect of 4-oxy and 4,5-dioxy substituents on the photochemical conversion of 2-methylbenzaldehydes to o-quinodimethanes (o-QDMs) has been studied.The presence of a 4-methoxy, or a 4 and 5-methoxy substituent prevented the photochemical formation of the o-QDM whereas 4-acetoxy and 4,5-diacetoxy-2-methylbenzaldehyde and the corresponding mesylates and tosylates were successfully converted to the o-QDMs.
