SiliaBond® Carbonate (Si–CO3) is the silica bound equivalent of tetramethyl ammonium carbonate. It can be used as a general base to quench a reaction, to free base amines in their ammonium salt form and to scavenge acids and acidic phenols, including HOBt, which is widely used in amide coupling reactions.
SiliaBond Carbonate is also very efficient at scavenging boronic acids: 99% removal of phenylboronic acid with one equivalent in DCM at room temperature after 1h. Si-CO3 can free base ephedrine hydrochloride quantitatively (100% yield determined by 1H NMR) using 4 equivalents at room temperature for two hours.
