, p. 3631 - 3634 (1996)
2,4,6-Trimethylcyclohexa-2,4-dien-1-one derivatives undergo ring cleavage to furnish amides on irradiation with visible light in the presence of various amines. Seven different amides containing a substituted diene moiety were synthesized in 87-95% yield.

A stable sulfone derivative of 2,4,6-trimethylcyclohexa-2,4-diene-1-one (7) undergoes facile ring cleavage under visible light to produce a ketene intermediate, which could be efficiently captured by amines to give amides even in the presence of competing

A convenient synthesis of a variety of 2,4-cyclohexadien-1-ones 3-7 is deseribed. Reaction of various phenols 2 having appropriate substituents with an excess of S,S-dimethylsuccinimidosulfonium chloride (Corey-Kim reagent, 1) in the presence of triethyla
Reaction of Phenols with t-Butyl Bromide-Dimethyl Sulphoxide. Methylthiomethylation versus Bromination
Dossena, Arnaldo,Marchelli, Rosangela,Casnati, Giuseppe
, p. 1141 - 1144 (2007/10/02)
t-Butyl bromide-activated dimethyl sulphoxide reacts with phenols to give either methylthiomethylation or bromination products.Several equilibria are shown to be simultaneously present in the system; however, by appropriate choice of several parameters (basicity, temperature, and reactant ratio) it is possible to drive the reaction selectively in one direction.A general discussion on the mechanism of these reactions is given.
