2/ New radical processes

Our group has a strong interest in photoredox catalysis and we have developed several pathways for the activation of C-X bonds for the formation of alkyl or aryl radicals.

  • Activation of C-O and C-N bonds of epoxides or aziridines
  • C-O reductive cleavage : photocatalytic Barton-McCombie deoxygenation

  • Silicates as radical precursors
    In 2015, we have devised the first photocatalytic oxidation bis-catecholato silicates to provide unstabilized primary radicals. These radicals can be engaged in radical reactions (allylations, conjugate additions) and in nickel-catalyzed cross-coupling reactions (dual catalysis).
Angew. Chem. Int. Ed. 201554, 11414, doi : 10.1002/anie.201504963 Link
Org. Chem. Front. 20163, 462, doi : 10.1039/c5qo00437c  Link

Various electrophiles can be used in the Ni-catalyzed cross coupling with alkyl radicals, for instance acylchorides. Reactions can be improved by flow synthesis.

Org. Chem. Front. 20196, 1378, doi : 10.1039/C9QO00092ELink

In collaboration with Profs. Ryu and Fukuyama, multicomponent reactions involving a carbonylation step have been devised. 3 components to make ketones, 4 components to make amides !

  • Use of non innocent ligands (NILs) in organometallic catalysis (C-H insertion and radical trifluoromethylation)

3/ Merging of gold catalysis with photoredox catalysis or photosensitization (energy transfer).

Upon blue LED irradiation, we have evidenced a dichotomic evolution of a reaction involving a vinylgold intermediate that depends on the electrophillc partner and the reaction conditions. With an aryldiazononium partner, a photoredox cycle is taking place generating an aryl radical which adds to gold (I) and which connects with the gold catalysis cycle to yield benzofurans.

J. Org. Chem. 201681, 7182, doi:10.1021/acs.joc.6b01060 Link

In contrast, with an alkynyliodide, the first example of photosensitization of the vinylgold intermediate has been demonstrated.

Nat. Chem. 201911, 797, doi : 10.1038/s41557-019-0295-9 Link

4/ Heterochemistry

Sulfur chemistry, radical reactions (homolytic substitutions), bis-sulfoxide derivatives as reagents and ligands)

Silicon chemistry : new Lewis acids

We study the interactions of Martin’s spirosilane with different nucleophiles, from anionic ones to bulky Lewis bases.

Org. Lett., 2013, 15, 748-751
J. Org. Chem., 2016, 80,3280

An access to new NHC derivatives has been open.
