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.

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.

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.

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 ...

Polymerization studies on allylic compounds. IV. Methallylic compounds

Journal of Polymer Science Part A-1: Polymer Chemistry, 1970
AbstractThe free‐radical polymerization of a series of 2‐methyl‐3‐substituted propenes was investigated. These compounds were found to homopolymerize with difficulty to give low molecular weight polymers. Their effect upon the polymerization of methyl methacrylate and styrene was investigated by rate and viscosity measurements.

Polymerization of allyl compounds. IV. Emulsion polymerization of allyl acetate

Journal of Polymer Science, 1948
AbstractThe emulsion polymerization of allyl acetate yields a polymer of the same average molecular weight as is obtained in bulk polymerization. The decomposition of potassimn persulfate is of the first order but is greatly accelerated by the presence of allyl acetate or of ethyl acetate.

Ruthenium-Catalyzed Allylation of Aromatic Compounds and Allylic Ether Formation

Organometallics, 2004
Ruthenium-catalyzed allylation of aromatic compounds such as benzene, toluene, p-xylene, anisole, phenol, furans, and thiophenes with allylic alcohol derivatives gives the corresponding allylated products in good to high yields with a high regioselectivity.

α-Selective Allylation of Azo Compounds Using Allylic Barium Reagents

Synlett, 2013
The addition of allylic barium reagents to azo compounds was achieved with high α-regioselectivity. The double-bond geometry of allylic barium reagents was retained throughout the reaction at –78 °C and E- or Z-enriched allylic hydrazines were selectively obtained from the corresponding allylic barium reagents.
