Fifty amidinium dithiocarbamates, many of which are ionic liquids at room temperature, have been prepared in situ by adding one equivalent of CS2 to an equimolar mixture of an amidine and an amine. Instead of reverting to their original molecular components when heated (as do the analogous amidinium carbamates), the more thermally stable amidinium dithiocarbamate salts undergo interesting thermolysis reactions whose pathways have ...
