SUMMARY:Conférence avec le Professeur Naoto Chatani (Osaka)
DESCRIPTION:Titre : New Chelation-Assisted Transformations of C-H Bonds Uti
 lizing a Bidendate Directing Group.Cette conférence sera prononcée (en 
 anglais) par le Professeur Naoto Chatani du Département de chimie appliqu
 ée de la Osaka University (Japon).Résumé : Chelation-assistance is now 
 one of more reliable methods for transforming C-H bonds. These reactions p
 ermit the highly regioselective transformation of C-H bonds proximal to a 
 coordinating functional group into a new C-X bond. A wide variety of funct
 ional groups has been evaluated as directing groups to date in the transfo
 rmation of C-H bonds. However\, in spite of the tremendous progress made t
 o date\, the development of new types of directing groups continues to be 
 important\, in terms of exploring novel types of transformations of C-H bo
 nds that cannot be achieved by conventional directing groups. In 2005\, Da
 ugulis reported the arylation of unactivated C(sp3)-H bonds using 8-aminoq
 uinoline and picolinamide as a N\,N-bidentate directing group in conjuncti
 on with Pd(OAc)2 as the catalyst. Encouraged by these promising results\, 
 a number of transformations of C-H bonds have since been developed using s
 imilar chelation systems. Herein\, we will present some new transformation
 s of C-H bonds by taking advantage of N\,N-bidentate directing groups\, su
 ch as 2-pyridynylmethylamine and 8-aminoquinoline in the presence of trans
 ition metal complexes.  Information supplémentaire
