Photochemie diarylsubstituierter 2H‐Tetrazole. VI. Quantenausbeuten der Photolyse diarylsubstituierter 2H‐Tetrazole

Photochemistry of Diarylsubstituted 2H‐Tetrazoles. VI. Quantumyields of the Photolysis of Diarylsubstituted 2H‐Tetrazoles The photoexcitation of diarylsubstituted 2H‐tetrazoles in ethanol in the presence of methylmethacrylat (MMA) yields quantitatively 1,3‐diaryl‐Δ2‐pyrazolines. The photoreactions investigated are spectroscopically uniform. The influence of the substituents on the quantum yields of the photolysis of 2H‐tetrazoles (1a—1x) is discussed.
