It is a synthetic aromatic hydrocarbon with six methyl groups stemming from the carbon centres of the ring. Hexamethylbenzene has historical significance in the field of X ray crystallography . In 1929, Kathleen Lonsdale first proved the shape of hexamethylbenzene and thus showed that the benzene ring is hexagonal and flat. ref The Structure of the Benzene Ring in Hexamethylbenzene, Proceedings of the Royal Society 123A 494 1929 . ref Uses Hexamethylbenzene has no significant commercial uses. The six methyl groups enhance the proton affinity of the central ring. ref Earhart, H. W., and Andrew P.

Martin Arthur Bennett Fellow of the Royal Society FRS is a Australian inorganic chemist . He gained recognition for studies on the coordination chemistry of tertiary phosphines, olefins, and acetylenes, and the relationship of their behavior to homogeneous catalysis . Professional career Born in London, Bennett received his PhD with Geoffrey Wilkinson at Imperial College . He was subsequently a researcher at University College, London with Ronald Nyholm and then with Arthur Adamson. While in London he discovered what is now known as Wilkinson s catalyst RhCl PPh sub 3 sub sub 3 sub . ref name Bennett Bennett, M. A. Longstaff, P. A. Complexes of Rhodium I with Triphenylphosphine. Chem. Ind. London 1965, p. 846. ref In the 1960 s he took a position in the Research School of Chemistry at the Australian National University in Canberra. Contributions At ANU, Bennett developed several lines of research broadly on themes in organometallic chemistry . These included pursuing his previous work on RhCl PPh sub 3 sub sub 3 sub , but focused on the Ir derivative which undergoes ortho metallation to the hydride HIrCl PPh sub 3 sub sub 2 sub Ph sub 2 sub PC sub 6 sub H sub 4 sub . ref Bennett, Martin Arthur D.
