PROCESS FOR THE PREPARATION OF SQUARIC ACID BY REDUCTIVE CYCLOTETRAMERIZATION OF CARBON MONOXIDE

A process for preparing dihydroxycyclobutenedione ("squaric acid") and squaric acid complexes and salts which comprises electrochemical cathodic reductive cyclotetramerization of carbon monoxide to produce the squarate anion, while preventing anodic reactions from substantially interfering...
