The effect of pressure on the oxidation of hydroarenes 3-9 with 2,3-dichloro-5,6-dicyano-1,4-quinone (DDQ; 1 a) or o-chloranil (10), leading to the corresponding arenes, has been investigated. The activation volumes were determined from the pressure

The electron-transfer-catalyzed rearrangement of the housanes 5 affords regioselectively only the two cyclopentenes 6 (CH(3) migration) and 7 (R migration) by 1,2-migration of the two groups at the methano bridge to the methyl terminus. The 1,2-shift

The utility of high pressure for the understanding of chemical reactions and its application in organic synthesis is shown for cycloadditions (inter- and intramolecular Diels-Alder reactions, 1,3-dipolar and [2+2] cycloadditions), cheletropic reactio

Unsaturated silyl enol ethers are irradiated in the presence of electron transfer sensitizers. The efficiency of the cyclization reaction using different sensitizers is investigated. The endo/exo regiochemistry of the ring closure reaction can either
