The unambiguous discrimination between 1-substituted and 2-substituted tetrazoles as well as between 1,5- and 2,5-disubstituted tetrazoles by means of homonuclear NOE difference spectroscopy is described.

An Environmentally Friendly Method for<i>N</i>-Methylation of 5-Substituted 1<i>H</i>-Tetrazoles with a Green Methylating Reagent: Dimethyl Carbonate
An environmentallyfriendlymethod was established for the N‐methylation of the 5‐substituted 1H‐tetrazoles with a greenreagent: DMC. DABCO was the optimal catalyst, and hazardous chemicals were avoided in this protocol. A plausible catalytic mechanism is proposed, which consists of a DABCO‐activated process and a thermally induced rearrangement of tetrazole carbamates.
