Abstract

Similarly, 2, 3, 4, 5, 6-pentabromotoluene yielded quantitatively pentabromobenzaldehyde, mp 281-283'. Both aldehydes were completely free of the corresponding acids, probably as a result of steric crowding in E, which prevents the removal of the third hydrogen from the benzylic carbon. The aldehyde-forming reaction seems to be characteristic of polyhalotoluenes and meta-substituted benzenes (m-xylene and mesitylene), since ...
