Synthesis and crystal structures of 4,4'-methyl-enebis(2,6-di-ethyl-aniline) and 4,4'-methyl-enebis(3-chloro-2,6-di-ethyl-aniline).

ABSTRACT: The title compounds 4,4'-methyl-enebis(2,6-di-ethyl-aniline) (C₂₁H₃₀N₂, 1) and 4,4'-methyl-enebis(3-chloro-2,6-di-ethyl-aniline) (C₂₁H₂₈Cl₂N₂, 2) are of significant inter-est as curing agents for a wide range of resins and as building blocks for sterically demanding compounds in the synthesis of ligands for catalysis. This paper describes their synthesis and the preparation of single crystals, with their structures determined through single-crystal X-ray analysis. The presence of the chlorine substituent slightly affects the twist angle between the two aromatic components. The mol-ecules of compound 1 form a network structure through inter-molecular N-H⋯N bonds and C-H⋯π inter-actions, while i
