- W2025741777 abstract "Die durch direkte Lichtanregung ausgelöste Isomerisierung einiger Tetracyclo[4.3.0.02,4.03,7]-non-8-en-Derivate 12 zu den Pentacyclo[4.3.0.02,4.03,8.05,7]nonan-Analogen 16 wird beschrie-ben. Die Spezifität dieser formalen [2π + 2σ]-Cycloadditionen ist entscheidend von der Art des Lösungsmittels abhängig. Durch Pyrolyse des Di-tert-butylperesters 16c läßt sich das Grundsystem 16a zu 50% gewinnen. Die Pentacyclen 16 sind thermisch beständig und gehen mit „bishomodienophilen”︁ Partnern keine Additionen ein. Die Strukturen der bei der Darstellung von 12b aus Norbornadien und Acetylendicarbonsäure-dimethylester isolierten 1:4- bzw. 2:2-Addukte werden als 19 bzw. 21 aufgeklart. Photochemical [2π + 2 σ] Cycloaddition Reactions in the Tetracyclo[4.3.0.02,4.03,7]non-8-ene Systeml) The isomerization upon direct photoexcitation of some tetracyclo[4.3.0.02.4.03,7]non-8-ene derivatives 12 to the pentacyclo[4.3.0.02,4.03,8.05,7]nonane analogs 16 is described. The specificity of this formal [2π + 2σ] cycloaddition reaction is determined by the nature of the solvent. Pyrolysis of the di-tert-butyl perester 16c affords the parent hydrocarbon 16a in 50% yield. The pentacyclic compounds 16 are thermally very stable and do not add „bishomodienophilic”︁ reagents. The structures of two minor 1:4 and 2:2 adducts obtained in the reaction of norbornadiene with dimethyl acetylenedicarboxylate are isolated and characterized as 19 and 21, respectively." @default.
