Metalation and derivatization of all six dichlorobenzotrifluorides: Site selectivities

Fabrice Cottet, Carla Bobbio, Eric Masson

The metalation of 2,3-, 2,6-, 2,4- and 3,5-dichlorobenzotrifluorides can be readily effected with std. reagents such as lithium diisopropylamide, lithium 2,2,6,6-tetramethylpiperidide, and butyllithium at the chlorine-adjacent 4- and 3-positions and the ch ...

New insight into the chemistry of allymetals

Eric Masson

The present thesis work provides new insight into the generation of allylmetal species and into their reactivity toward electrophiles. endo-Allylpotassiums are known to be more stable than their corresponding exo-isomers. The ring strain of methylenecycloa ...

Are reactions between allylpotassiums and halotrimethylsilanes diffusion-controlled?

Eric Masson

The order of reactivity (X = F < Cl < Br < I) determined for the reaction of the model nucleophile pinenylpotassium with halotrimethylsilanes XSi(CH3)(3) in hexane and with halotriisopropylsilanes XSi(iC(3)H(7))(3) in tetrahydrofuran supports a single-step ...

pi-Arene/Metal Binding: An Issue Not Only of Structure but Also of Reactivity

Eric Masson

A trimethyl-, triethyl-, or triisopropylsilyl group attached to the meta position of toluene retards the rate of permutational H/metal interconversion with butyllithium in the presence of K tert-butoxide by factors of 1.7, 3, and 7, resp. Although remote f ...

Relay propagation of crowding: the trifluoromethyl group as both an emitter and transmitter of steric pressure

Rosario Scopelliti, Fabrice Cottet, Christophe Heiss, Eric Masson

Whereas lithium 2,2,6,6-tetramethylpiperidide (LITMP) abstrs. a proton exclusively from the 4-position of 3-bromobenzotrifluoride, the same base attacks selectively the 2-position when employed in the presence of N,N,N',N'',N''-pentamethyldiethylenetriamin ...

Fluoronaphthalene building blocks via arynes: A solution to the problem of positional selectivity

Eric Masson

When 3-fluoro- and 3-chloro-1,2-didehydrobenzenes are generated in the presence of 2-(trimethylsilyl)furan, two regioisomeric cycloadducts are formed in a 1:2 ratio. However, regioselectivity can be installed by fitting one bulky trimethylsilyl group into ...
