Subsupercritical Water Generated by Inductive Heating Inside Flow Reactors Facilitates the Claisen Rearrangement
Oltmanns, Mona,Kirschning, Andreas
, p. 1942 - 1946 (2020/11/13)
Claisen rearrangement of electron-deficient O-allylated phenols, including fluorine-modified phenols, is facilitated in aqueous media at high temperatures and pressures under flow conditions, as opposed to organic solvents. The O-allylation of phenols can be coupled with the Claisen rearrangement in an integrated flow system.

A general route for the stereoselective synthesis of (E)-(1-propenyl)phenyl esters by catalytic CC bond isomerization
Díaz-álvarez, Alba E.,Crochet, Pascale,Cadierno, Victorio
body text, p. 2611 - 2620 (2012/05/20)
A general and efficient procedure for the stereoselective synthesis of (E)-(1-propenyl)phenyl esters from readily accessible allylphenols has been developed. The process involves a two-step sequence consisting of the initial acylation of the allylphenols with an acid chloride, followed by catalytic CC bond isomerization in the resulting allylphenyl esters. The latter step was performed in methanol at 80 °C using catalytic amounts (0.5 mol %) of the commercially available bis(allyl)-ruthenium(IV) dimer [{RuCl(μ-Cl) (η3:η3-C10H16)} 2] (C10H16=2,7-dimethylocta-2,6-diene-1,8-diyl) . Reactions proceeded in high yields (68-93%) and short times (4-9 h) with complete E-selectivity.
