Organic salts of dinitromethane

Seven new salts of dinitromethane (DNM) with organic bases were prepared by two different methods: either by neutralisation of dinitromethane solutions with appropriate base or by metathesis reactions between DNM sodium salt and a respective organic base salt. Crystal structures of formamidinium dinitromethanide, acetamidinium dinitromethanide and propionamidinium dinitromethanide and 1H and 13C chemical shifts of all compounds were determined. The new salts have been characterized in terms of their thermal stability.
