Choi, P. published the artcileConversion of 3-azido-5-phenyl-1,2,4-oxadiazole into benzoyl cyanide; a new thermal fragmentation, Recommanded Product: 3-Bromo-5-phenyl-1,2,4-oxadiazole, the main research area is azidophenyloxadiazole preparation thermal decomposition; oxadiazole azido phenyl preparation pyrolysis; benzoyl cyanide.

Flash vacuum pyrolysis at 550° of the title azide (I), prepared in 50% yield by heating the corresponding 3-bromo compound with KN3/18-crown-6 or LiN3 in anhydrous THF at 90°, gave 70% PhCOCN. The transformation is explained by conversion of the azide into its tetrazole tautomer and thence to a pentaazafulvene (II) by N-O bond cleavage. Loss of N2 gives BzNC which rearranges to PhCOCN.

Choi, P. published the artcileReaction of 3-azido-5-phenyl-1,2,4-oxadiazole with dimethylformamide, a new deoxygenative coupling reaction, HPLC of Formula: 23432-94-2, the main research area is azidophenyloxadiazole deoxygenative coupling DMF; oxadiazole azido deoxygenative coupling; methylaminooxadiazole; aminomethyleneaminooxadiazole.

Heating the bromooxadiazole I (R = Br) with NaN3 in anhydrous DMF at 130° for 3 h gave the oxadiazoles I (R = NMe2, N:CHNMe2) in 39 and 34% yield, resp. The latter is formed by a new deoxygenative coupling of the azide I (R = N3) (the product of the reaction at 90°), or the nitrene derived from it, with DMF.

Humphrey, Guy R. published the artcileA novel synthesis of 3-bromo-1,2,4-oxadiazoles, Recommanded Product: 3-Bromo-5-phenyl-1,2,4-oxadiazole, the main research area is dipolar cycloaddition bromocyanogen oxide nitrile; bromoxadiazole.

The synthesis of 3-bromo-1,2,4-oxadiazoles I (R = Me2CH, cyclopropyl, EtO2C, PhCH2, Ph, 4-O2NC6H4, ClCH2, BrCH2) by 1,3-dipolar cycloaddition between BrCNO and RCN (same R) is described. Thus, Br2C:NOH in PhCN was treated with NaHCO3 to give 40% I (R = Ph) along with a small amount of the dimer II.
