Sustainable and cost-efficient electro-synthesis of formamidine acetate from cyanamide in aqueous acidic electrolyte

Abstract: Formamidine represents a versatile buidling block in synthetic organic chemistry. We developed a new electrochemical synthesis of formamidine acetate by cathodic reduction of cyanamide in an aqueous electrolyte and in...

“…This offered a significant increase in energy efficiency. [100] The over-potential for the OER at graphite is only slightly higher than that of IrO 2 at 10 mA cm À 2 . [101] However, the potential for the C-oxidation of a graphite surface into CO or CO 2 is very low.…”

“…Replacing the graphite anode by a MMO anode in a flow cell led to the yield of formamidine acetate being increased, while the cell voltage decreased at same time. This offered a significant increase in energy efficiency [100] . The over‐potential for the OER at graphite is only slightly higher than that of IrO 2 at 10 mA cm −2 [101] .…”

“…Dies führt zu einer erheblichen Steigerung der Energieeffizienz. [100] Die Überspannung für OER ist an Graphit nur geringfügig höher als an IrO 2 bei 10 mA cm À 2 . [101] Allerdings ist das Potential für eine C-Oxidation an der Graphitoberfläche zu CO und CO 2 sehr gering.…”

“…Based on the experience of our lab in the dehydrogenative coupling of (thio-)amides [25] and the use of cyanamide as a potent building block in electroorganic conversions, [26] we designed a novel and very simple to perform protocol for the synthesis of several N-cyanosulfilimines in good to excellent yield. Since additional strong bases and halo-based oxidizers represent the source of waste in the conventional synthetic approach we tried to omit them by direct electrosynthesis.…”
