Polymorphism in secondary benzene sulfonamides

The role of about 20 different solvents in the crystallization of polymorphs for 13 N-phenyl benzene sulfonamides was studied. Five compounds (1, 2, 3, 7, and 11) are dimorphic, and one is trimorphic (6). All the crystalline solids were characterized by p

Synthesis of 2,6-disubstituted and 2,3,6-trisubstituted anilines

A number of 2,6-disubstituted and 2,3,6-trisubstituted anilines have been prepared via the selective para dehalogenation of the corresponding anilines. Modification of the substituents on the amino nitrogen demonstrates that the selectivity is derived from steric rather than electronic effects. The effects of the choice of formate hydrogen donor, Pd catalyst, solvent, and temperature upon the efficiency and selectivity of the dehalogenation are discussed.
