3H-azepines and related systems. Part 2. The photolyses of aryl azides bearing electron-withdrawing substituents

Photochemistry of fluorophenyl azides in aniline

“…[19][20][21][22]. In another study [7], photolysis in diethylamine of aryl azides 15 bearing an ortho substituent (R ¼ CH 3 , C 2 H 5 , i-C 3 H 7 , C 6 H 5 ) gave a single isomeric azepine 16.…”

2-Azido-1-(3,6-dichloro-9H-fluoren-1-yl)ethanone

“…For the mutagenic activity of azides, see: Sander & Muehlbour (1977); Nilan et al (1973); Owais et al (1983). For the preparation of 1,2,3-triazoles via 1,3-dipolar cycloaddition reactions of azides with substituted acetylene compounds, see: Purvisis et al (1984); Patei & Smalley (1984). For a related fused-ring structure, see: Molins et al (2002).…”

“…The chemistry of azides has thus attracted the attention of many chemists, since many of these compounds play an important role in organic chemistry. One of the more useful synthetic applications of azides is the preparation of 1,2,3-triazoles via 1,3-dipolar cycloaddition reactions of azides with substituted acetylene compound (Purvisis et al, 1984;Patei & Smalley, 1984). The crystal structures of 4-Azidomethyl-7-methyl-2-oxo-2H-chromene-6-sulfonyl azide (Basanagouda et al, 2010) and 2-Azidomethyl-3-methyl-1phenylsulfonyl-1H-indole (Karthikeyan et al, 2011) have been reported.…”

Modification of styrene polymer by attaching suitable groups as side chain

“…One of the more useful synthetic applications of azides is the preparation of 1,2,3-triazoles via 1,3-dipolar cycloaddition click reactions of azides with substituted acetylene compounds [16][17][18][19].…”
