Abstract 13 C NMR chemical shifts of 69 substituted methanes (general formula R 1 R 2 R 3 R 4 C, where the substituents were H, C 6 H 5 , Cl, OH, OR, imidazol‐1‐yl, pyrazol‐1‐yl, 1,2,4‐triazol‐1‐yl, 1,2,4‐triazol‐4‐yl, benzimidazol‐1‐yl, indazol‐1‐yl, indazol‐2‐yl, benzotriazol‐1‐yl and benzotriazol‐2‐yl) are reported. The effects of the various N ‐substituents on the 13 C chemical shifts of the heterocyclic nuclei are reported. The chemical shifts of the methane carbon atom are discussed using an interactive model. Some 1 H‐ 13 C coupling constants have been measured.
Abstract Bei der Umsetzung von Benztriazol (I) mit Methylenchlorid (II) bzw. Chloroform (VI) unter Phasentransfer‐Bedingungen werden die Verbindungen (III)‐(V) bzw. (VII)‐(IX) erhalten.
Abstract Die Azole (I) reagieren mit den Chlormethanderivaten (II) unter Phasen‐ Transfer‐Katalyse zu den Polyazolylmethanen (III), die z.Tl. in Form von Isomeren‐ Gemischen (Alkylierung unterschiedlicher N‐Atome) anfallen.
