Arylative Ring Expansion of 3-Vinylazetidin-3-Ols and 3-Vinyloxetan-3-Ols to Dihydrofurans by Dual Palladium and Acid Catalysis
Qian Wang, Jieping Zhu, Takuji Fujii
In contrast to the well-studied 1-vinylcyclobutanols, the reactivity of 3-vinylazetidin-3-ols 1 and 3-vinyloxetan-3-ols 2 under transition metal catalysis remains largely unexplored. We report herein their unique reactivity under dual palladium and acid ca ...
Wiley-V C H Verlag Gmbh2024Metal-Stabilized Boronate Ester Cages
Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Erica Giraldi
Molecular cages with arylboronate ester caps at the vertices are described. The cages were obtained by metal-templated polycondensation reactions of a tris(2-formylpyridine oxime) ligand with arylboronic acids. Suited templates are triflate or triflimide s ...
2021Alkynyl Triazenes as Fluoroalkyne Surrogates: Regioselective Access to 4-Fluoro-2-pyridones by a Rh(III)-Catalyzed C–H Activation–Lossen Rearrangement–Wallach Reaction
Kay Severin, Nicolai Cramer, Carl Thomas Bormann, Jin Fay Tan
Fluorinated pyridones are an important scaffold displaying relevant biological activities. Efficient assembly strategies of pyridones are transition metal-catalyzed C–H annulations with alkynes. The inaccessibility and extreme lability of fluoro alkynes re ...
2020Contributions to the Chemistry of N2O and 1-Alkynyltriazenes
This thesis describes the utilization of nitrous oxide N2O as an oxidant in oxidative cou-pling reactions and as a nitrogen atom donor in the synthesis of 1-alkynyltriazene and further reactivity of the latter. An overview of N2O and its reactivity is give ...
EPFL2018"New methods for indoles and [3,4]-fused oxindoles syntheses" and "Copper-catalyzed/mediated difunctionalization of alkenes with alkylnitriles"
Two main topics were addressed in this manuscript: (1) New methods for indoles and [3,4]-fused oxindoles syntheses; (2) Copper-catalyzed/mediated difunctionalization of alkenes with alkylnitriles. Given the omnipresent character of the indole and oxindole ...
EPFL2014Acid-Induced Degradation of Phosphorescent Dopants for OLEDs and Its Application to the Synthesis of Tris-heteroleptic Iridium(III) Bis-cyclometalated Complexes
Mohammad Khaja Nazeeruddin, Rosario Scopelliti, Ursula Röthlisberger, Ivano Tavernelli, Basile Curchod, Julien Edouard Frey
Investigations of blue phosphorescent organic light emitting diodes (OLEDs) based on [Ir(2-(2,4-difluorophenyl)pyridine)(2)(picolinate)] (FIrPic) have pointed to the cleavage of the picolinate as a possible reason for device instability. We reproduced the ...

A series of cationic metalla-cycles of the general formulae (eta(6)-p-cym)(4)Ru-4(OO boolean AND OO)(2)(N boolean AND N)(2) and (eta(6)-p-cym)(4)Ru-4(NO boolean AND NO)(2)(N boolean AND N)(2) has been prepared from the dinuclear arene ruthenium ...
2011simple physical model for the simultaneous rationalisation of melting points and heat capacities of ionic liquids
The anal. of potential energy surfaces of ion pairs within the framework of an anharmonic oscillator model allows rationalization and prediction of m.ps. (Tmp) and heat capacities (Cp) of ionic liqs. (ILs) comprising di- and trialkylimidazolium or tetraalk ...
Royal Society of Chemistry2010The regiochemically flexible functionalization of fluoro-and trifluoromethyl-substituted indoles
The use of organometallic reagents for functionalization of arenes and heterocycles has recently been renewed by our group. The use of bulky trialkylsilyl groups allows one to shield an acidic position by steric hindrance and the introduction of a chlorine ...
EPFL2005The organometallic approach to the functionalization of five- and six-membered nitrogen heterocycles
The present thesis work concerns the preparation and optionally site selective functionalization of five- and six-membered nitrogen heterocycles and the investigation of atropisomerism of α,o-bis(methoxymethyl)-1-phenylindole. Mono- and disubstituted 2-bro ...
