Branch selective allylation of acetylacetone catalyzed by Water-soluble rhodium complex catalyst

[RhCl(1,5-cod)]2/PTA is highly active branch-selective catalyst for C-allylation of acetylacetone by allylic carbonates in water/ethyl acetate biphasic system, where either crotyl or 1-methylallyl carbonates gives sterically congested branched allylation product, suggesting formation of a common allylrhodium intermediate.

Rhodium/Lewis Acid Catalyzed Regioselective Addition of 1,3-Dicarbonyl Compounds to Internal Alkynes

Herein we describe an efficient protocol for the regioselective addition of 1,3-dicarbonyl compounds to internal alkynes catalyzed by rhodium/Lewis acid catalysts. The corresponding branched/linear allylic alkylation products could be selectively obtained in good yields. Rh-H species were considered to be generated by direct C-H oxidative addition of 1,3-dicarbonyl compounds with rhodium catalyst with the assistance of Lewis acid. Moreover, a retro-allylic alkylation process was observed in this transformation.

Iridium/ N-Heterocyclic Carbene Complex-Catalyzed Intermolecular Allylic Alkylation Reaction

N-Heterocyclic carbenes (NHCs) were found to be suitable ligands in Ir-catalyzed intermolecular allylic alkylation reaction. In the presence of a catalyst derived from [Ir(dncot)Cl]2 (dncot = dinaphthocyclooctatetraene) and triazolium salt L7,

New 1,2,4,5-tetrakis-(N-imidazoliniummethyl)benzene and 1,2,4,5-tetrakis-(N-benzimidazoliummethyl)benzene salts as N-heterocyclic tetracarbene precursors: synthesis and involvement in ruthenium-catalyzed allylation reactions

New tetraimidazolinium and tetrabenzimidazolium salts have been prepared. Upon reaction with tBuOK, they generate carbene ligands, which were associated in situ to [RuCp*(MeCN)3]PF6 to produce new ruthenium catalysts that

Efficient metal-catalyzed direct benzylation and allylic alkylation of 2,4-pentanediones

(Chemical Equation Presented) A highly effective metal-catalyzed benzylation and allylic alkylation of 2,4-pentanediones has been developed. This new bismuth-catalyzed direct carbon-carbon bond forming reaction provides the corresponding monoalkylated dicarbonyl compounds in high yields after short reaction times using the lowest amounts of catalyst (1 mol %) and the free alcohol. In addition, a new route to substituted indenes is presented.

Regioselective allylic alkylation and etherification catalyzed by in situ generated N-heterocyclic carbene ruthenium complexes

Benzimidazolium halides are used for the first time as ligand precursors in ruthenium-catalyzed substitution of allylic carbonates and chlorides by carbon nucleophiles and phenols, respectively. After generation of diaminocarbene species upon deprotonatio

Direct carbon-carbon bond formation from alcohols and active methylenes, alkoxyketones, or indoles catalyzed by indium trichloride

(Chemical Equation Presented) The unsalted variety: The direct coupling reaction of alcohols with active methylenes, alkoxyketones, or indoles catalyzed by InCl3 proceeds without the formation of metal salts (see scheme). As H2O is the only by-product of this system, the alkylated products are easily isolated in pure form, and the reaction is suitable for large-scale synthesis.

Ruthenium-bisimine: A new catalytic precursor for regioselective allylic alkylation

New complexes [Cp*Ru(bisimine)Cl] are active catalysts for the regioselective alkylation of allylic carbonates by soft carbonucleophiles, in favour of the branched isomers. The catalysts can be conveniently prepared in situ from [Cp*Ru(cod)Cl] and a bulky aromatic bisimine.

Copper(I) promoted C-C bond forming reactions: direct activation of allyl alcohols

Allylic alcohols, acetates, carbonates and chlorides can be activated by copper(I) salts towards nucleophilic substitution by carbon nucleophiles under relatively mild conditions.
