3-Dimethyl-3H-pyrazoles were photolyzed, and in the presence of 2,4,6-triphenylpyrylium tetrafluoroborate (TPP+) as a sensitizer in acetonitrile; in addition to cyclopropenes, 2H-pyrroles were obtained as solvent adducts to 1,3-radical cation intermediate.
3,3-二甲基-3H-吡唑被光解,并在乙腈中作为敏化剂的2,4,6-三苯基吡咯四氟硼酸盐(TPP+)存在下;除了环丙烯之外,2H-吡咯作为溶剂加合物与 1,3- 自由基阳离子中间体获得。
