Abstract

Pentaalkylmethylguanidinium methylcarbonates 6 can easily be prepared from pentaalkylguanidines 5 and dimethyl carbonate (DMC) in a sustainable solvent-free synthesis. Most of the title compounds are room temperature ionic liquids (RTILs) which provide convenient access to halide-free guanidinium-based ILs (GILs) 7via acid–base reactions and subsequent decarboxylation, similar to industrially important imidazolium methylcarbonates 1.
