indolines. The scope and mechanism of this cyclisation have been explored. Moreover, benzaldehyde tosylhydrazones with o-alkoxy-, o-thioalkyl-, and o-phosphonate substituents as well as the corresponding diazoalkanes were pyrolysed and photolysed. The products from these carbene precursors were compared with those obtained from the analogous nitrene precursors [i.e. ArN3 or ArNO2+(RO)3P].
邻二烷基氨基取代的苯甲醛的甲苯磺酰的热分解和光分解产生二氢吲哚。已经探索了这种环化的范围和机理。此外,苯甲醛甲苯磺酰腙与ø -烷氧基- ,ø -thioalkyl-,和ø -膦取代基以及相应的重氮烷进行热解和光解。从这些前体的碳烯的产物与来自类似的氮宾的前体[获得的那些进行比较即ARN 3或ARNO 2 +(RO)3 P]。
