The preparation of a range of tetraalkylformamidinium salts for use as precursors for the formation of stable diamino-and amino-carbenes was discussed. The preparation methods included nucleophilic addition to formamides followed by trapping with electrophiles such as triflic anhydride and various methods of formamide activation. Exchange reactions involving orthoesters, the transamination of amidinium salts and alkylation methods were other methods suitable for the synthesis.
