Intramolecular Nitrene Insertion into Aromatic and Heteroaromatic Rings. Part 9. Synthesis of 2-Azidodiphenylmethanes and the Kinetics of their Thermal Decomposition in Solution

The synthesis of some new o-azidodiphenylmethanes 3b, 10, 15, 18, 21 and 22 is described.The first-order kinetics of the thermal decomposition in trichlorobenzene of these and some previously studied azides (3a, 3c and 3d) has been studied in the range 140-180 K.The initial step is evolution of nitrogen and formation of a nitrene intermediate, which reacts to give a 10H-azepinoindole together with some amine.Rate constants for the first step were compared with those for product formation and show it to be the rate-determining factor.Electron-donating substituentspara to the azide group stabilise the incipient nitrene by resonance interactions (rate constants correlate with ?R+) yielding higher proportions of amine products, which result from the spin forbidden singlet-triplet nitrene transition.Substituents at the 4'-position influence the nature of the products but not decomposition rates.A new compound, 1a-methoxy-1a,9b-dihydro-1H-cyclopropapyridolindole (28), is obtained from 2-azido-4'-methoxydiphenylmethane (3d) in addition to the expected azepinoindole and amine.Kinetic measurements show that it is an intermediate in one, but not the sole, route to formation of 8-methoxyazepinoindole 27 from 3d.

Thermal Interconversion and Cyclisation Reactions of 2-(Arylthio)benzyl Radicals and 2-(Benzyl)thiophenoxyl Radicals

Generation of the title radicals by flash vacuum pyrolysis leads to thioxanthene(s) as the sole significant product(s).Cyclisation takes place via an intermediate spirodienyl radical .

Azonia-azulenes. Part 6. Photochemical Addition of Alcohols to 10H-Azepinoindoles

Irradiation of solutions of the azepinoindole (1) in methanol or ethanol gives the 6- and 9-alkoxy-6,9-dihydroazepinoindoles (5), (24), (4), and (23); the other major products are the benzocyclobutaindolizines (6) and (25).Other substituted azepino

Chemical process

Aromatic amines (e.g., aniline) are selectively alkylated in an ortho nuclear position by reaction with an olefin (e.g., ethylene) in the presence of an aluminum anilide catalyst. Hydrogen halides (e.g., HCl) are added to increase the reaction rate.
