Treatment of 4-tert-butyl-3,3-dimethyl-5-methylene-Δ1-1,2,4-triazoline (3) with benzonitrile oxide (9), diphenylnitrile imine (10), phenyl azide, and p-nitrophenyl azide led, in each case, to 1,3-dipolar cycloaddition. The products, Δ1-1,2,4-tri-azolines that are spiro-fused to another 5-membered ring, could be isolated in pure form in three of the four cases. All four are thermally unstable and decompose by loss of N2 from the Δ1-1,2,4-triazoline moiety to form an azomethine ylide. Subsequent reactions of those ylides are described.

“…The title compound was prepared from azidobenzene according to the reported method (El Khadem et al, 1968). The colourless prisms (average size: 0.5×0.8×1.0 mm) were obtained by slow evaporation from 95% ethanol/water solution at room temperature.…”

The title compound, C10H9N3O2, was synthesized from azidobenzene and ethyl acetylacetate. A pair of hydrogen bonds [2.617 (2) Å] interconnects a pair of the carboxyl groups, forming an R 2 2(8) inversion dimer, a frequent motif in carboxylic acids. In the title structure, the bonding H atom in the aforementioned O—H⋯O hydrogen bond is significantly shifted towards the acceptor O atom [the donor and acceptor O—H distances are 1.25 (4) and 1.38 (4) Å, respectively]. A plot of the O⋯O versus O—H distances in compounds with paired carboxyl groups shows that the title structure belongs to the group of structures with abnormally long O—H distances with regard to the O⋯O contacts. The displacement of the bonding H atom towards the centre of the hydrogen bond is concomitant with more equal C—O bonding distances in the carboxyl group.

Some 1-aryl 1,2,3-triazoles

Abstract: A number of 1 -aryl 1.2.3-triazoles have been synthesised; their U.V. absorption data and the apparent dissociation constants of the derived carboxylic acids are given. 1 -Aryl 1,2,3-triazoIes are nitrated and brominated in the 4-position of the phenyl ring.
