- W2160159286 abstract "Die Thermolyse von 1 -Pyrazolinen mit Elektronenakzeptorgruppen in 3-Stellung wird bezüglich Produktverteilung und kinetischen Parametern eingehend untersucht. Die Ergebnisse deuten darauf hin, daß in protonischen Lösungsmitteln bevorzugt ein zweistufiger Zerfall stattfindet. Sterische Effekte können jedoch auch zur Bevorzugung eines einstufigen Prozesses führen. Kupfersalze beschleunigen die Zersetzung und verursachen eine völlige Umkehr des Produktverhältnisses zugunsten der Cyclopropanderivate. On the Mechanism of the Thermolysis of 1-Pyrazolines) Thermolysis of 1 -pyrazolines containing electron withdrawing groups in position 3 has been thoroughly investigated with reference to product distribution and kinetic parameters. The results point to a two-step mechanism in protonic solvents. Steric effects can lead to the preference of a one-step process. Copper salts accelerate the decomposition and completely reverse the product distribution in favour of the cyclopropane derivatives." @default.
