Synthesen mit Acetylenverbindungen, V. Über die Darstellung von Bi‐[1.2.3‐triazolylen]

Abstract: Durch Anlagerung von Azidoverbindungen an Diacetylen-dialkohole konnten in guten Ausbeuten Vertreter der bisher unbekannten Bi-[I .2.3-1 H-triazolyle] dargestellt werden. In einigen Fsllen waren dagegen nur die Mono-triazolyl-Verbindungen zu erhalten. Bisher sind drei Grundtypen von Bitriazolylen bekanntgeworden. Zunachst sind die Bi-[l.2.4-1 H-triazolyle]-(3.3') (I) 2) zu nennen, deren beide Ringe uber C-Atorne miteinander verknupft sind. Das 4-[ 1.2.4-1 H-Triazolyl-(3)]-l.2.4-4H-triazol(II)3) besitzt dagegen… Show more

“…On removing the trimethylsilyl groups 1-methyl-4,5-diethynyl-1,2,3-triazole was obtained. EXPERIMENTAL 1 H and 13 C NMR spectra were registered on a spectrometer Bruker DPX-300 (operating frequencies 300 and 75.5 ΜHz respectively), internal reference TMS, solvent acetone-d 6 . IR spectra were recorded on a spectriphotometer Specord 75IR from 3% solutions of compounds.…”

“…The reaction product, the corresponding bis-triazole, was isolated in 70% yield [5]. The reaction of 2,7-dimethylocta-3,5-diyne-2,7-diol with methylazide or ethylazide in cumene at 100°C in sealed ampules in 24 h provided bis-1,2,3-triazole in 83 and 86% yield respectively [6]. The reaction of unsubstituted diacetylene with phenylazide gave either 1-phenyl-5-ethynyl-1,2,3-triazole in 63% yield or the corresponding bis-adduct in 55% yield depending on the molar ratio of the components.…”

“…The reaction shown in Equation (4) is interesting because it highlights the fact that the core of the bistriazole unit is chiral. The bistriazole core of 1 has not previously been reported with this substitution pattern (although regioisomeric materials have been made) 8. Figure 1 shows a molecular representation from a single‐crystal X‐ray analysis of compound 1 e .…”
