The electron-poor vinylcyclopropanes in organometallic catalysis: interesting skeletons with various reactivities
Maxime Laugeois, Maxime Vitale, Véronique Michelet, Virginie Ratovelomanana-Vidal

Vinylcyclopropanes are molecules with extremely rich reactivity and among these, the electron-deficient vinylcyclopropanes have a "donor-acceptor" type polarization which gives them a particular reactivity. This article presents on the one hand the main routes of synthesis of electron-deficient vinylcyclopropanes under stoichiometric and catalytic conditions. On the other hand, the reactivity of the vinylcyclopropanes is presented in the presence of homogeneous organometallic catalysts: the rearrangement processes, functionalization reactions via ring opening and catalytic (3 + 2) cycloaddition reactions.

Functionalization of 2-bromo acrolein acetals through halogen-metal exchange reaction
Quentin Llopis, Gérard Guillamot, Phannarath Phansavath, Virginie Ratovelomanana-Vidal

This literature overview presents the functionalization of 2-bromoacrolein acetals to their lithiated
equivalents by halogen-metal exchange reaction and their addition to electrophiles. The transformation of these organolithium reagents into organocuprates is also presented, as well as their use in conjugated addition or nucleophilic substitution reactions.
