Allylation of Epoxides with Allylic Indium Reagents.

ChemInform, 2004
Allylindium sesquihalide reacts with epoxide to give homoallyl alcohol via a 1,2-shift reaction. In contrast, allylindate gives the ring-opening product without rearrangement.

Telomerization Studies with Allyl Ethene Sulfonate and Allyl Allyl Sulfonate

Journal of Macromolecular Science: Part A - Chemistry, 1971
Abstract Telomerization of allyl ethene sulfonate (AES) in the presence of butyl mercaptan yielded a mixture of two products: the first was a five-membered ring sultone containing a sulfide group and the second a five-membered ring sulfonium salt formed by reaction of the sultone of the Just product with its own sulfide function.

Kinetics and Mechanisms of the Allyl + Allyl and Allyl + Propargyl Recombination Reactions

The Journal of Physical Chemistry A, 2011
The kinetics and mechanisms of the self-reaction of allyl radicals and the cross-reaction between allyl and propargyl radicals were studied both experimentally and theoretically. The experiments were carried out over the temperature range 295-800 K and the pressure range 20-200 Torr (maintained by He or N(2)).

Allyls

2014
This chapter addresses the importance and usage of the commercially low volume thermoset plastics group known as allyls. The three significant sub-elements of this group are poly(diallylphthalates), poly(diallylisophthalates), and poly(allyldiglycol carbonate). Chemistry, processing, and properties are also described.

Multicomponent decarboxylative allylations

Chem. Commun., 2014
The reaction of Meldrum's acid, pyrrolide, and allyl carbonates allows a multicomponent decarboxylative coupling to form allylated acyl pyrroles. This strategy is made possible by the in situ formation of β-oxo carboxylates from Meldrum's acid. Subsequent decarboxylative enolate formation and electrophilic allylation complete the reaction.

Regioselektive Allyl‐Allyl‐Kreuzkupplungen ohne Übergangsmetallkatalysator

Angewandte Chemie, 2016
AbstractDie Reaktion von Allylzinkhalogeniden mit Allylbromiden in einer 1:1‐Mischung aus THF und DMPU liefert selektiv 1,5‐Diene nach einem SN2‐ähnlichen Mechanismus. Die Allylzinkverbindung reagiert an der sterisch stärker gehinderten Seite (γ‐Position) des Allylsystems und liefert ausschließlich die γ,α′‐Allyl‐Allyl‐Kreuzkupplungsprodukte ...

Catalytic, Nucleophilic Allylation of Aldehydes with Allyl Acetate

Organic Letters, 2008
A new catalytic allylation of aldehydes has been developed that employs allyl acetate as the allylating reagent. Under catalysis by ruthenium trichloride (3 mol %) in the presence of carbon monoxide (30 psi), water (1.5 equiv), and triethylamine (0.1 equiv), a wide range of aromatic, olefinic, and aliphatic aldehydes are efficiently allylated under ...
