Gas-phase generation of benzonitrile N-methyl-imide (3) leads to rearrangement to 1-methylene-2-benzylidenehydrazine (5) and methylphenylcarbodi-imide (9); the latter is also obtained in 85% yield by flash vacuum pyrolysis of 1-methyl-5-...
Benzotriazoles are preparatively useful precursors of cyanocyclopentadienes, carbazoles, and aza-analogues. FVP of 5-aryltetrazoles can result in double N elimination with formation of arylcarbenes or of heteroarylcarbenes, which again ...
The flow-vacuum pyrolyses of 13,14-dihydro-8H-tetrazolo[1,5a]dibenzoazonine (14) and 8H-tetrazolo[1,5a]dibenzoazonine (10) at 1 Torr and 500掳C respectively 375掳C were studied by GC/MS. The main reaction product of 14 is the ring contra...
The photolysis of tetrazoles has undergone extensive research. However, there are still some problems to be solved in terms of mechanistic understanding an...
Photolysis of 1‐phenyltetrazole 2b at either 193 or 266 nm in a Ne matrix as well as flash vacuum pyrolysis (FVP) of the same compound with isolation of t...
vacuum pyrolysis or photolysis, in particular nitrenes and carbenes derived from azides, diazo compounds, triazoles, and tetrazoles and characterized in low ...
A reinterpretation of the spectroscopic data for the products of flash vacuum pyrolysis (FVP) of 8- and 9-membered polymethylenetetrazoles 1, 3, 5, and 7 w...
Tetrazoles are important synthons in synthetic organic chemistry and also used as pre-cursors of carbenes in flash vacuum pyrolysis [3]. The nitrogen ...
Pyrolysis of 1,2,3,3a,8,8a-hexahydro-2,3,8-methenocyclopentindene in a flow system at 1.33 mbar, in an argon atmosphere and at temperatures between 500 and...
