Sixteen new ionic liquids, including three room temperature ionic liquids, possessing cations derived from monoquaternization of DABCO have been identified through systematic variation of cation alkyl chain length and anion structure. The DABCO salts are obtained in good to excellent yields and show melting point trends, with respect to cation alkyl chain length, consistent with those reported for the imidazolium series of ionic liquids.
