Electrocarboxylation of Other Substrates

As noted above, during the past few years the electrocarboylation of several other substrates [6-7, 55-79] involving alkenes [55-58], alkynes [58-60], aldehydes [61], aliphatic ketones [62], imines [63], aryldiazonium tetrafluoroborates [63], derivatives of cinnammic acid [64—66] has been investigated by many groups. 

Dunach, Inesi and others also investigated the electrochemical synthesis of cyclic carbonates from C02 with epoxides, alcohols and glycols [66]. In this regard, Yang et al. [67] reported the use of pure room temperature ionic liquids (ILs) as reaction media in the electrochemical activation of C02 for the synthesis of cyclic carbonate from epoxide, under mild conditions. C02-saturated IL (BMIMBF4) solutions were also used for the electrochemical carboxylation of activated olefins [68]. Monocarboxylic acids were obtained in moderate yield (35-55%), and the IL was recycled five times.
