\nRésumé:
\n 
\nHypervalent 
 iodine (HVI) reagents hold tremendous potential in the development of new 
 synthetic methods\, whether by devising fundamentally new reactions\, or b
 y diverting the course of known processes. Over the past several years\, w
 e have developed new fluorinated motifs from diazos and hydrazones\,[1] wh
 ich exploit a HVI reagent’s oxidative  and/or ligand transfer potential
 . We have been equally interested in using HVI compounds as substrates and
  catalysts to develop new C-C bond-forming reactions. This led to new cycl
 opropane and dihydrofuran syntheses\,[2] which has now evolved to exploit 
 blue LEDs to initiate such reactions from iodonium ylides. This talk will 
 highlight our most recent work on fluorinative rearrangement reactions (1\
 , 2)\, on interrupted Wolff-Kishner reductions that incorporate the -CF3 g
 roup (3)\, and on the synthesis of carbocycles and/or heterocycles (4\, 5)
  using HVI catalysis or LED irradiation.

\nBiographie:
\n 

 \nGraham Murphy received his Ph.D. from the University of Alberta\, where 
 he worked in the laboratory of Dr. F.G. West on using oxonium ylides in th
 e synthesis of fused\, medium-sized rings. He held a JSPS postdoctoral fel
 lowship at Tohoku University with Dr. Masahiro Hirama\, an NSERC postdocto
 ral fellowship at Colorado State University with Dr. J.L. Wood\, and he wa
 s a postdoctoral fellow supported by the Biorefining Conversions Network a
 t the University of Alberta. He began his independent career in 2011 at th
 e University of Waterloo\, Canada\, and was promoted to Associate Professo
 r with Tenure in July 2017. He is a recipient of numerous awards\, includi
 ng the Thieme Chemistry Journal Award and the Province of Ontario Early Re
 searcher Award. His independent research program concerns developing novel
  reactions mediated by hypervalent iodine reagents.
