Abstract: Organoaluminum (aluminum phenolate and aluminum isopropylate) and acidicheterogeneous catalysts (zeolites C-10, C-100 and ZSM, clay KSF, sulfonic cationexchangers Fiban K-1 and Amberlist 36 Dry) were studied in the alkylation of4-methylphenol wi

Prenylphenols and 2,2-dimethylbenzopyrans were synthesized via alkylation of phenol and hydroquinone with prenol in the presence of organoaluminum catalysts, i.e., aluminum phenoxide and isopropoxide. Reaction products were isolated and characterized. Sev

Allylic and benzylic alcohols are converted into corresponding unsymmetrical ethers when reacted with various orthoesters in the presence of montmorillonite KSF at ambient temperature. A detailed study has been undertaken to examine the mechanism and generality of these reactions with regard to various acidic catalysts, which reveal interesting competitive reactions mainly O-acetylation, together with trace amount of dimerized product. The type of the side product and their relative quantity depends upon the nature of the catalyst employed. Furthermore, the low yields of the Claisen rearrangement product obtained from allylic alcohols under heating is rationalized due to the formation of some of these products.

Butyltin trichloride, as a catalyst precursor, promotes the following processes: (i) etherification of 2,3-unsaturated alcohols, (ii) etherification of functional diols, (iii) cyclization of 2,5-hexanedione, and (iv) dehydration of cyclic diols.Many examples are reported.
Cetonisation catalytique du methyl-2-butene-3-ol par des complexes du rhodium(III) ou du palladium(II)
Derdar, Fatma,Martin, Jacques,Martin, Claudine,Bregeault, Jean-Marie,Mercier, Jacqueline
, p. C21 - C26 (2007/10/02)
A number of efficient catalytic procedures for the oxidation of acid-sensitive substrate such as 2-methyl-3-buten-2-ol to the corresponding ketone (2-methyl-butan-2-ol-3-one) are compared.Reaction with dioxygen (or quinone) and a palladium precursor (PdCl2 or ) under mild conditions (=35 deg C), gave good conversions (98percent) and good selectivities (=90percent).
