Eco-friendly acetylcholine-carboxylate bio-ionic liquids for controllable: N-methylation and N-formylation using ambient CO2 at low temperatures

Catalytic fixation of CO2 to produce valuable fine chemicals is of great significance to develop a green and sustainable circulation of excessive carbon in the environment. Herein, a series of non-toxic, biodegradable and recyclable acetylcholine-carboxylate bio-ionic liquids with different cations and anions were simply synthesized for producing formamides and methylamines using atmospheric CO2 as a carbon source, and phenylsilane as a hydrogen donor. The selectivity toward products was tuned by altering the reaction temperature under solvent or solvent-free conditions. N-Methylamines (ca. 96% yield) were obtained in acetonitrile at 50 °C, while N-formamides (ca. 99% yield) were attained without a solvent at 30 °C. The established bio-ionic liquid catalytic system found a wide range of applicability in substrates and possessed a high potentiality in scale-up to gram-grade production. The developed catalytic system was fairly stable, which could be easily reused without an apparent loss of reactivity, possibly due to the strong electrostatic interactions between the cation and anion. The combination of experimental and computational results explicitly elucidated the reaction mechanism: PhSiH3 activated by a bio-IL was favorable for the formation of silyl formate from hydrosilylation of CO2, followed by a reaction with an amine to give an N-formamide, while an N-methylamine was formed by further hydrosilylation of the N-formamide.

Process for producing a high purity quaternary ammonium hydroxide

A process for production of high purity quaternary ammonium hydroxides, comprising electrolyzing quaternary ammonium hydrogencarbonates represented by the general formula: (wherein the symbols are as defined in the appended claims) in an electrolytic cell comprising an anode compartment and a cathode compartment defined by a cation exchange membrane. In accordance with this process, high purity quaternary ammonium hydroxides can be produced with high electrolytic efficiency and further without causing corrosion of equip-ment. Since the quaternary ammonium hydroxides produced by the present invention are of high purity, they can be effectively used as, for example, cleaners, etchants or developers for wafers in the production of IC and LSI in the field of electronics and semiconductors.
