Abstract

Phosphonate monoester long-chain and functionalized ammonium ionic liqs. were prepd. by a two-step process, comprising SN2 alkylation of Me methylphosphonate monoester and reaction of the mixed neutral diester (R1O)(MeO)P(O)R2 with a 1-R-imidazole, resulting in preferential Me transfer and formation of the ionic liqs., 1-R-3-methylimidazolium (RMIM) salts [RMIM]+[(R1O)MePO2]- (R = Et, R1 = CH2CN, CH2CO2Me, Bu, C8H17). Some salts were prepd. also by R1 transfer to methylimidazole from sym. phosphonate diesters (R1O)2P(O)R2 [R1 = C8H17, Me(OCH2CH2)3, C12H25, Bu; R2 = Me, Ph]. The resulting ionic liqs. can be obtained in pure form, free of chloride and water. [on SciFinder(R)]
