Nitrenes, diradicals, and ylides. Ring expansion and ring opening in 2-quinazolylnitrenes (2006)

Kvaskoff, D., Bednarek, P., George, L., Waich, K., Wentrup, C.

Tetrazolo[1,5-a] quinazoline (9) is converted to 2-azidoquinazoline (10) on sublimation at 200 degrees C and above, and the azide-tetrazole equilibrium is governed by entropy. 2-Quinazolylnitrenes 11...

3-pyridylcarbene and 3-pyridylnitrene: Ring opening to nitrile ylides (2003)

Bednarek, P., Wentrup, C.

Photolysis of 3-pyridyldiazomethane in an Ar matrix at 7-10 K gives 3-pyridylcarbene. Further photolysis causes ring opening to nitrile ylide 26 (formonitrile pent-2-en-4-ynylide) as the major...

Methoxy(2-pyridyl)ketene (2003)

Andersen, H. G., Bednarek, P., Wentrup, C.

Matrix photolysis of 3-methoxycarbonyl-1,2,3-triazolo[1,5-a]pyridine (12) affords s-E-2-pyridylketene (4), but flash vacuum thermolysis of 12 gives methoxy(2-pyridyl)ketene (15), predominantly in the...
