Allylation of ?-benzeneruthenium bichloride with allyl compounds of mercury

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1974
The reaction ofπ-benzeneruthenium dichloride with the allyl compounds of mercury gaveπ-benzene-π-allylruthenium halides that contain substituents in theπ-allyl group.

Iron-Catalyzed Electrochemical Allylation of Carbonyl Compounds by Allylic Acetates

The Journal of Organic Chemistry, 2003
Homoallylic alcohols were synthesized from aldehydes or ketones and allylic acetates, using an electrochemical process catalyzed by iron complexes. We first studied the reactivity of allyl acetate, using N,N-dimethylformamide (DMF) or acetonitrile (AN) as solvent, FeBr(2) as catalyst, and Fe as the sacrificial anode.

Direct conversion of allylic nitro compounds into allyl sulphides and allyl sulphones

Journal of the Chemical Society, Chemical Communications, 1985
Allylic nitro compounds are directly converted into allyl sulphides or allyl sulphones with high regioselectivity on treatment with sodium benzenethiolate alone or with sodium benzenesulphinate in the presence of a catalytic amount of Pd(PPh3)4.

The role of biotransformation in the genotoxicity of allylic compounds

Archives of Toxicology, 1987
Allylic compounds exert direct genotoxic activities which depend on the chemical nature of the leaving group and on further substituents. Besides the direct genotoxic effects, metabolic activation mechanisms are also conceivable. Epoxidation seems to play a minor role in bioactivation, whereas the metabolic formation of strongly mutagenic alpha, beta ...

Photoinduced Allylation of Aromatic Carbonyl Compounds by Allylic Stannanes

Chemistry Letters, 1987
Abstract Irradiation of aromatic carbonyl compounds and allyl-, 2-methyl-2-propenyl-, or 3-methyl-2-butenyltrimethylstannanes in acetonitrile afforded δ,γ-unsaturated alcohols as major product. A photoinduced electron transfer mechanism is proposed for the allylations.

Palladium-catalysed allylic alkylations of allylic nitro-compounds

Journal of the Chemical Society, Chemical Communications, 1982
In the presence of catalytic amounts of tetrakis(triphenylphosphine)palladium, allylic nitro-compounds undergo allylic alkylations with sodium dimethyl malonate.

Gold-catalysed allylic alkylation of aromatic and heteroaromatic compounds with allylic alcohols

Organic & Biomolecular Chemistry, 2008
Friedel-Crafts allylic alkylation of a wide variety of aromatic and heteroaromatic compounds with allylic alcohols catalysed by AuCl(3) (5 mol%) under mild conditions at room temperature was accomplished in good to excellent yields (up to 99%) and regioselectivity.

Allyl compounds

1994
This chapter focuses on allyl alcohols, which are renowned for their ease of oxidation. It refers to manganese dioxide, which is highly effective for bringing about the oxidation of primary allylic alcohols to the αβ-unsaturated aldehydes. It also describes a highly-selective oxidation of allylic alcohols that involves epoxidation of the carbon-carbon ...
