From the results of sensitization and quenching experiments it is concluded that the photolysis of 3H-indazoles 6a and 6b in solution proceeds from the excited singlet state.
从敏化和淬灭实验的结果可以得出结论,溶液中的3H-吲唑6a和6b的光解是从激发单重态开始的。

The [3+2] cycloaddition of a variety of diazocompounds with o-(trimethylsilyl)aryl triflates in the presence of CsF or TBAF at room temperature provides a very direct, efficient approach to a wide range of potentially biologically and pharmaceutically interesting substituted indazoles in good to excellent yields under mild reaction conditions. Simple diazomethane derivatives afford N-unsubstituted
