Interesting material with which the mechanism of decomposition of organic azides was investigated is triphenylmethyl azide... 

The stable silylene 756 was reacted with triphenylmethyl azide to give a silanimine (757) (equation 250)335. 

In a number of ways the reactions of stable silylenes resemble those of phosphines, R3P, to which they are isolobal analogs. Examples are provided by the reactions of 59 with covalent azides. Phosphines are known to react with azides to give phosphineimines, Ph3P=NR. In similar fashion, 59 reacted with triphenylmethyl azide in THF to give the silanimine 72 as its THF complex (equation 109)148. This reaction provides a new method for synthesizing compounds containing Si=N double bonds, which have previously been made by salt elimination reactions375.

Triphenylmethyl azide and 9-phenyl-9-fluorenyl azide give quite stable 1 1 adducts with triphenyl phosphine, which decompose only at elevated temperatures in neutral solvents at rates which appear... 

Photolysis of the aryl-alkyl azide CH CPhaNa showed that the migratory aptitudes of the methyl and phenyl groups were almost identical and this and the formation of triphenylmethyl amine from irradiation of triphenylmethyl azide in the presence of efficient hydrogen donors were taken to confirm the existence of discrete nitrene intermediates. Although the occurrence of a triplet-sensitized decomposition from alkyl azides and triphenylmethyl azides (the... 

Lewis and Saunders have studied the sensitized photorearrangement of ring-substituted triphenylmethyl azides. 

Deb and Yoffe [66] compared the photochemical decomposition of mercury(I) azide with that of triphenylmethyl azide. The first step in the decomposition is suggested to be the fission of the longer N-N bond of the azide group. Results were compared with data for reactions of inorganic azides and it was concluded that there is no clear distinction between the energy requirements of the two classes of azides, covalent and ionic. Deb [67] has determined the electron energy levels of several azides and correlated the band structures with observed stabilities. 

As an example. Figure 1.6 shows the DSC measurement of triphenylmethyl azide (trityl azide) applying a linear heating rate of only l.OK/min (sample size 3.35mg, Argon atmosphere, A1 pan with pierced lid). Endothermic processes are displayed by negative...
