Shock Sensitivity of a Vinamidinium Bis-Perchlorate Reagent and Demonstration of a Lower Energy Alternative
31 December 2000 (online)
"Vinamidinium" bis-perchlorate salt 1 (2-dimethylaminomethylene-1,3-bis(dimethylimmonio)-propane bis-perchlorate) was found to possess remarkably high thermal energy as well as significant shock sensitivity. A reported method for preparation of 2,5-disubstituted pyrimidines with 1 was of interest, and we found that the corresponding bis-tetrafluoroborate salt 2 was equally effective in this transformation, while possessing significantly lower thermal energy.
