Description / Table of Contents:
Photochemie konjugierter Stickstoff - Carbonyl-Systeme, 6. - Photodimerisierung von 2,4-Dioxotetrahydropyridinen.Bei Bestrahlung in Acetonitril liefern 2,4-Dioxotetrahydropyridine 1, die Schlüssel-Verbindungen mit konjugiertem Stickstoff - Carbonyl-System, trans-syn Photodimere 2 als Hauptprodukte. Bestrahlung der N-Methylen-verknüpften Bis(2,4-dioxotetrahydropyridine) 3 führt sehr rasch zu Cyclobutan-Derivaten 4.
Notes:
On irradiation in acetonitrile solution, 2,4-dioxotetrahydropyridines 1, the key compounds of conjugated nitrogen - carbonyl systems, undergo photodimerization to afford the trans-syn dimers 2 as major products. Irradiation of N-methylene-linked bis(2,4-dioxotetrahydropyridines) 3 led to rapid photoreaction to give 4.
