This work was undertaken to determine whether tetra-p-tolyltin could be used to prepare para substitution products of toluene free from the ortho isomers and also whether the side chain entered into any of these reactions. The formation of pure p-nitrotoluene is noteworthy in this connection. Since the substitution of a methyl group in the benzene ring enhances the activity of the ring, tetra-p-tolyltin should be very reactive toward enter-ing substituents. Its ...
