SiliCycle™ SiliaBond™ Functionalized Silica Gels, Cyanoborohydride (CBH), 40 to 63 μm, 60 Å
Our Cyanoborohydride (Si-CBH) is very useful in reductive amination and in the reduction of imines and aldehydes.
Supplier: SiliCycle™ R66730B100G
SiliaBond™ Cyanoborohydride (Si-CBH) is the silica-bound equivalent of sodium cyanoborohydride. Bound cyanoborohydride is very useful in reductive amination and in the reduction of imines and aldehydes. Cyanide contamination of products is a concern when using the solution phase equivalent. This problem is minimized with the use of silica-bound materials, since the toxic cyanide residue remains on the silica. Additionally, it may be used to reduce α, β-unsaturated carbonyl to the corresponding unsaturated alcohol.
To determine if any cyanide ion was leaching from the silica, 1 g of SiliaBond™ Cyanoborohydride was washed in 10 mL of methanol for 24 hours. Cyanide strips indicated less than 3 ppm in each test performed.
