Versuchsvorschrift

A 150 mL glass ampule equipped with a grease free high-vacuum PTFE valve and a TEFLON™ coated stir bar was flamed-out under vacuum. Inside the dry-box, the ampule was loaded with 1.18 g (8.00 mmol) 3,5-dinitro-1H-1,2,4-triazole and 61.6 mg (2.00 mmol) ammonia borane. The ampule was connected to a vacuum line, evacuated and cooled to −196° C. About 10 mL of dry dimethoxyethane was slowly condensed into the ampule. The ampule was closed and allowed to warm to ambient temperature. After 30 minutes, the ampule was heated to 110° C. for eight hours. The obtained yellow solution was cooled to −196° C. and 5.9 mmol of evolved hydrogen was pumped off. The reaction mixture was allowed to warm to ambient temperature. Subsequent evacuation to a constant weight over 24 hours resulted in a yellow solid of ammonium tetrakis(3,5-dinitro-1H-1,2,4-triazolyl)borate, 8.0 mmol.
