Nitrenes aromatic groups

The IR spectrum of the effusion gives a strong absorption peak at lT Ocm due to v(C=0) of carbonyl group. This absorption indicates that the aziridine was oxidized on the silicagel surface. Because of such a fact, silicagel can not be used for the analysis of the reaction products of aromatic nitrene with unsaturated olefines. The present experiment, therefore, was repeated by replacing silicagel with alumina. [Pg.193]

In suitable solvents even alkyl nitrenes produce small amounts of primary amines . Carbethoxynitrene abstracts hydrogen from hydrocarbons (12%) and more efficiently from alcohols (90%). Aromatic nitrenes are in general less reactive than carbonyl nitrenes, they abstract hydrogen, provided the attack on unreacted azido groups... [Pg.463]
