supporting information; experimental part, p. 2713 - 2718 (2011/12/04)
AgOTf is an effective catalyst for intermolecular allylation of aromatic and heteroaromatic compounds with allylic alcohols affording allylated arenes in up to 99% yields. Heterogeneous allylation of arenes catalyzed by Ag 3PW12O40 gave comparable product yields to those obtained by AgOTf. Ag3PW12O40 could be reused five times with slightly decreased activity.

scheme or table, p. 2835 - 2840 (2010/10/04)
Here we report a simple procedure for the synthesis of a novel hybrid catalyst by growing iron oxide nanoparticles on carboxy-functionalized graphite. This hybrid catalyst demonstrated superior catalytic activity towards the alkylation of arenes with alkyl halides in contrast to commercial graphite or unsupported iron oxide nanoparticles in terms of yields and general applicability. The catalyst can be reused up to five times with a minimal loss of catalytic activity. Georg Thieme Verlag Stuttgart.
Efficient and selective alkylation of arenes and heteroarenes with benzyl and allyl ethers using a Ir/Sn bimetallic catalyst
Podder, Susmita,Roy, Sujit
, p. 9146 - 9152 (2008/02/09)
A high-valent heterobimetallic catalyst namely [Ir2(COD)2(SnCl3)2(Cl)2(μ-Cl)2] (5 mol %), or dual catalyst system of [Ir(COD)Cl]2 (1 mol %) and SnCl4 (4 mol %), promotes the benzylation or allylation of arenes and heteroarenes using ethers as the alkylating agents. An electrophilic mechanism is proposed from a Hammett correlation.
High-yield ruthenium-catalyzed Friedel-Crafts-type allylation reactions using dicationic RuIV catalysts
Fernandez, Ignacio,Hermatschweiler, Rene,Breher, Frank,Pregosin, Paul S.,Veiros, Luis F.,Calhorda, Maria Jose
, p. 6386 - 6391 (2007/10/03)
(Chemical Equation Presented) Unexpected linkage: The use of dicationic RuIV complexes in the Friedel-Crafts-type allylation of aromatic alcohols leads unexpectedly to the formation of a new C-C bond and not to the phenolation product (see sche
A convenient and improved montmorillonite K-10 catalysed Friedel-Crafts benzylation and allylation with activated esters
Karade,Shirodkar,Potrekar
, p. 652 - 654 (2007/10/03)
Benzyl benzoate and cinnamyl acetate has been effectively used respectively as alkylating and allylating substrates in Friedel-Crafts reaction catalysed by montmorillonite K-10 clay.
Molybdenum- and tungsten-catalyzed allylation of aromatic compounds with allylic esters and alcohols
Shimizu, Isao,Sakamoto, Toshiaki,Kawaragi, Saeko,Maruyama, Yooichiro,Yamamoto, Akio
, p. 137 - 138 (2007/10/03)
A novel method to substitute aromatic compounds with allylic groups using oxygen-containing allylic compounds in the presence of molybdenum or tungsten carbonyls under neutral conditions has been developed. The method is applicable to one step synthesis of methyl eugenol.
Allylation of arenes catalysed by thiolate-bridged diruthenium complexes
Nishibayashi, Yoshiaki,Yamanashi, Masashi,Takagi, Yukihiro,Hidai, Masanobu
, p. 859 - 860 (2007/10/03)
In the presence of catalytic amounts of cationic thiolate-bridged diruthenium complexes, arenes react with allylic alcohols to afford the corresponding allylated aromatic products in high yields.
