Chirality in Transition Metal Chemistry shows how transition metal chirality has an important role in coordination, organometallic and supramolecular systems, and discusses applications in organic synthesis, materials science, and molecular recognition.

Author Biography

Hani, Haniel Amouri, was born in Anapolis Goias (Brazil) and obtained his Ph.D. degree (1987) in chemistry from Universite Louis Pasteur Strasbourg (France), with Professor John A. Osborn, on the subject of homogeneous catalysis (hydrogenation). In 1988 he spent one year at Gif-sur-Yvette (France) as a post-doctoral fellow with Dr Hugh Felkin where he studied C-H activation of saturated hydrocarbon with transition metal polyhydrides. In 1992-1993 he spent one year at UC-Berkeley (USA) with Professor K. Peter C. Vollhardt and was working on the synthesis of oligocyclopentadienyl metal complex and their behaviour as electron transfer reagents. He is a Research Director in CNRS and is currently the director of the 'ARC' group (Auto-assemblage, Reconnaissance et Chiralite) of the IPCM at Universite Pierre et Marie Curie Paris-6. His main research interests are chirality, organometallic and coordination chemistry, and he has had over 90 research papers and reviews published in international scientific journals.

Michel Gruselle was born in Decazeville (France) and obtained his Ph.D. degree (doctorat d'Etat) in the CNRS laboratory of Thiais, a suburb of Paris, in 1975 with Dr Daniel Lefort where he worked on stereochemical problems in radical chemistry. In 1974 he joined Bianca Tchoubar's group and started working on nitrogen activation by organometallic complexes, and he spent some time collaborating with Prof. A.E. Shilov in Moscow. he is a Research Director in CNRS at Universite Pierre et Marie Curie Paris-6 and was the director of the ARC group (Auto-assemblage, Reconnaissance et Chiralite) at the IPCM from 1996-2000. His main research interests a4re enantioselective synthesis in coordination chemistry and in material science and he has had over 110 research papers and reviews published in international scientific journals.
