Utilisation des diazirines comme source d'azote électrophile pour la synthèse d'hydrazines et d'hétérocycles
… la faible diversité des produits obtenus. Les diazirines présentent un fort potentiel pour être utilisées comme alternative à ces préparations, puisque ces molécules peuvent réagir avec des nucléophiles pour donner les diaziridines substituées correspondantes, puis être hydrolysées pour …

Développement de catalyseurs pour la réaction d'halolactonisation énantiosélective et valorisation de diazirines comme source d'azote électrophile
… différent sera traité, celui de la chimie des diazirines. Actuellement, les diazirines sont utilisées principalement comme source de carbènes, mais dans cet ouvrage il sera démontré que les diazirines peuvent agir comme source d'azote électrophile. Cette propriété est très intéressante et sera …

Photochemistry of 5-Membered Heteroaryl(trifluoromethyl)carbenes in Low Temperature Matrices
… led us to a new realm of UV-vis transparent diazirines, which behave as normal diazirine photochemically, but have very weak n<em>f</em>à<em>f</em>x<em>f</em>nabsorptions which are not visible in experimental UV-vis spectra. Also, we were able to synthesize diazirine precursors of both 2- and …

MODIFIED BODIPY PROBES TO EXPLORE PEROXISOME FUNCTION
… and para methoxy substituted trifluoromethyl diazirines, were attempted these were not successful. In an alternative approach, 4-benzoylphenylboronic acid was used as the pro-photoaffinity labelling residue. This could successfully be coupled with iodo-BODIPY for future use as cell-labelling …

Matrix Isolation of Aryl(trifluoromethyl)carbenes, Heteroaryl(trifluoromethyl)carbenes and Phenylbis(trifluoromethyl)carbenes
… The 1- and 2-naphthyl(trifluoromethyl)diazirines, the precursors of 1- and 2-naphthyl(trifluoromethyl)carbenes, have dissimilar geometric structures leading to differentUV/Vis absorptions. In the studied pyridyl(trifluoromethyl)carbenes, 4-pyridyl(trifluoromethyl)carbene was the most …

Pioneering investigations into organometallic electrochemistry
… are also reported. In chapter 5, the use of diazirines as carbene precursors for carbon surface modification is investigated, via the synthesis and characterisation of diazirine derivatised cymantrene and cyrhetrene. The surface modification of glassy carbon electrodes was attempted via …
