Purp-[N.sub.3] (2a) and 5FU-[N.sub.3] (2b) were covalently anchored to MWCNTs using nitrene
chemistry yielding MWCNT>N-Purp (3aa) and MWCNT>N-5FU (3ab), respectively (Figure 3).
The decomposition reaction of aromatic sulfonyl azides when irradiated with UV light produces nitrogen gas and the nitrene

SIMPLIFIED CADOGAN REACTION BY MICROWAVE ENHANCED NITRENE
Chemists from the US, Mexico, Europe, and China who specialize in nitrene
chemistry highlight how spectroscopy and calculations have been used to characterize various nitrene
intermediates since the previous monograph on them appeared three decades ago.
After setting out principles and practice, they cover the photogeneration of carbon-centered radicals, heteroatom-centered radicals, biradicals and radical pairs, radical ions, carbocations and carbanions, and cargenes and nitrenes
. A final chapter describes how to manipulate intermediates the photochemical way.
In order to get functionalized with these active molecules, CNTs allow side-wall covalent attachment of functional groups by the addition of radicals, nucleophilic carbenes, nitrenes
, nucleophilic cyclopropanation, and electrophiles [79, 83, 84].

When heated, the azides decompose, forming nitrenes
, which are easily inserted into the C-H bonds, forming amines or amides.
