The palladium-catalysed α-chloro ketone methoxycarbonylation and allylic alkylation reactions can be efficiently combined to provide a new catalytic domino reaction. The first, carbonylative, step generates the β-keto ester, which acts as the nucle

We report here the stereoconvergent formylation of (E/Z)-β-bromo-β-fluorostyrene mixtures with carbon monoxide and sodium formate catalyzed by palladium. Optimization of reaction conditions leads to the corresponding pure (Z)-α-fluorocinnamaldehyd

The telomerization of butadiene with solketal (1,2-isopropylideneglycerol) in the presence of palladium complexes has been studied under aqueous biphasic conditions. This reaction followed by depro...

The palladium-catalyzed telomerisation of butadiene with glycerol has been studied under aqueous biphasic conditions both in the presence of a liquid phase of butadiene and under gaseous atmosphere of butadiene. In this last case, gaseous butadiene w

The rhodium-catalysed carbonylative addition of arylboronic acids to propargylic alcohols yields gamma-hydroxy enones that are readily cyclised through a dehydration step to the corresponding furan analogues. The transformation was improved thanks to

The carbonylative cross-coupling of potassium vinyl trifluoroborate or 2,4,6-trivinyltricycloboroxane with aryl iodides under mild conditions affords aryl vinyl ketones. The optimisation of the reaction conditions leads to the targeted enones in good

A 1,4-conjugate addition reaction between p-carboxyphenylboronic acid and methyl acrylate has been performed using a homogenous rhodium catalyst entrapped in the hydrophobic pores of hydrophobized ordered mesoporous silica. The catalyst-loaded inorga

The carbonylative addition of arylboronic acids to terminal alkynes under mild conditions affords (E)-α,β-unsaturated ketones with good yields. The reaction was achieved with chloro(1,5-cyclooctadiene)rhodium(I) dimer or chlorodicarbonylrhodium(I)

The palladium catalysed alkoxycarbonylation of trichloroethylene has been studied. Under standard conditions (with classical phosphine as ligand of Pd) no reaction takes place. On the other hand, we have shown that a simple procedure allows to conver

A new class of cationic alpha-cyclodextrins bearing 2-hydroxy-3-trimethylammoniopropyl groups has been synthesised. We investigated their efficiency as mass-transfer promoters in a biphasic hydroformylation reaction catalysed by a rhodium trisulfonat
