Hydrocarbon complexes, acid-soluble decomposition

Several authors have studied the reaction products in the Lewis acid catalyzed decomposition of phenyl and alkyl azides.179-185 Hoegerlee and Butler have found that phenyl azide forms a hydrocarbon-soluble complex at —70° with triethylaluminum, diethylchloroaluminum, and ethyldichloro-aluminum. 1 Upon warming to room temperature, this complex slowly decomposes into an intermediate phenylimine-aluminum compound (25) which then rearranges into a variety of amidoalkylaluminum reaction products (RP) (eq 4). 

Decomposition of Acid-Soluble Hydrocarbon Complexes. As re-ported earlier (11), it has been postulated that 2-butenes may react with the acid-soluble hydrocarbon cations (see Reaction E-2 of Table I). Isobutylene may also react similarly. The resulting acid-soluble ion could later decompose via 8-scission to release isobutylene ... 

All silver oxides, AgO, , x > 1, are very strong oxidants. They are soluble in cold nitric acid yielding dark brown solutions with the Ag ion complexed by NOj. These solutions will even oxidize saturated hydrocarbons. Both Ag20j and Ag304 decompose rapidly at temperatures of 50° and 60°, respectively. Even at room temperature, decomposition to AgO within a couple of hours is observed. Well-crystallized AgO, as obtained by electrocrystallization, is more stable and decomposes only above 160°.
