Description:Research Seminar\n\nNickel-catalyzed cross coupling reactions d
 riven by light represent a family of promising new methods to furnish carb
 on-hetoatom (C-N\, C-O\, and C-S) bonds which are highly sought after in m
 edicinal and process chemistry\, as well as in other fields. The developme
 nt of a novel C-N bond formation method between aryl halides and amines th
 at proceeds under mild conditions via photo-excitation of a Ni-amine compl
 ex with 365 nm light will be described first. Next\, we explore the questi
 on as to whether the same type of C-N bond forming reactions can proceed v
 ia energy transfer from an excited state photocatalyst to a Ni-amine compl
 ex\, a process which had not been explored mechanistically in dual catalyt
 ic (Ni and photocatalyst) reaction systems prior to the work described. In
  the final section of the talk\, an ongoing collaboration with the Johanne
 s Group at AstraZeneca is discussed in which we perform a mechanistic stud
 y of their unified C-N\, C-O\, and C-S coupling methodology\, for which we
  find a reaction pathway to be operative that to our knowledge has not yet
  been supported experimentally in any dual catalytic system to date.\n\nZo
