The cycloaddition of homo-1H-azepine

Journal of the Chemical Society D: Chemical Communications, 1970
Reactions of tetracyanoethylene and nitrosobenzene with 2,3-homo-1H-azepine (II) give the corresponding normal (4 + 2)π cycloadducts, and show that (II) reacts faster than its valence tautomer (I).

ChemInform Abstract: Synthetic Routes to Arylpyrido(2,3‐c)azepines and ‐(3,2‐c)azepines.

ChemInform, 1987
AbstractTreatment of (I) with (IIa) yields the phenylated product (IIIa); the chlorophenyl analogues (IIIb) and (IIIc), however, are not accessible by this procedure.

Cyclopentadienylcobalt complexes of some azepines

Journal of Organometallic Chemistry, 1995
The complexes [(C5R5)Co(2-5-η-C6H6Nr′)] (R′ = C(O)OEt; R = H (6a) or Me (9a)) are prepared from N-ethoxycarbonyl azepine and [(C5R5)Co(C2H4)2] (R = H 5 or Me (8)). On treatment with methoxide,ion, 6a is partially converted into N-methoxycarbonyl derivative 6b. Complex 9a can be reduced with LiAlH4 to give the N-methyl derivative 9b.

Das System Azepin‐Benzolimin

Chemische Berichte, 1973
AbstractMit Hilfe der erweiterten Hückel‐Methode werden a) die Gleichgewichtslage der Valenz‐isomerisierung 1H‐Azepin‐Benzol‐1,2‐imin, b) die Stärke der an dieser Isomerisierung beteiligten σ‐Bindung im Benzolimin und c) der Einfluß von Akzeptoren am Stickstoff auf das Gleichgewicht und auf die Stabilität des Azepins diskutiert.

Synthesis of 1-bromo-2-ethoxycyclopent[d]azepine. A route to cyclopent[d]azepine

Journal of the Chemical Society, Chemical Communications, 1980
The first derivative, 1-bromo-2-ethoxycyclopent[d]azepine, of the as yet unknown cyclopent[d]-azepine can be synthesized by dehydrogenation of 4,5,7,8-tetrahydro-2-ethoxycyclopent[d]azepine.
