DESCRIPTION:Prof. Kilian Muniz\, ICIQ\, Tarragona\, Spain\nThe first part 
 of the lecture will focus on concepts for palladium catalysed synthesis of
  vicinal diamines from alkenes.1\,2 Key methodology is the use of high oxi
 dation state metal catalysis such as palladium(IV) catalysis.3 These react
 ions have been elaborated for terminal and internal alkenes with and proce
 ed under complete regio- and diastereoselectivity.4\,5 The final products 
 can be converted readily into different ligand motifs.\nWithin our ongoing
  programme to develop new metal-free amination reactions\, we have recentl
 y reported novel transformations using defined hypervalent iodine reagents
  in combination with bissulfonimides as nitrogen sources.6 Unprecedented t
 ransformations of this type include the first enantioselective diamination
  of alkenes (eq. 2)7\,8 and first examples of selective diamination of but
 adienes.9 Related transformations including allylic amination10 and aminat
 ion of acetylenes11 will also be discussed.\n__________________\n(1) A. Ig
