Details

SiliaBond® Cyanoborohydride (SiCBH) 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 the product 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 see if any cyanide ion was leaching from the silica, 1 g of SiliaBond Cyanoborohydride has been washed in 10 mL of methanol for 24 hours. Cyanide strips indicated less than 3 ppm in each test performed.

Details

SiliaBond® Dimethylamine is a silica bound tertiary amine base that can be used in most applications requiring a tertiary amine, particularly as a HCl sponge. Silica bound ammonium salt by-products are easily separated by filtration. This dimethylamine immobilized on silica gel can be used as a base catalyst in Michael1or Knoevenagel2 reactions. It can also be used as a catalyst for alkane oxidation.3 Unlike polystyrene based resins, the amine is not a benzyl amine and therefore is not susceptible to cleavage by electrophiles.

Details

SiliaBond® Diol (Si-Diol) may be used as boronic acid scavenger in the same way as PS-DEAM.

SiliaBond Diol may also be used as polar sorbent in normal phase and aqueous size exclustion chromatography. Like bare silica, SiliaBond Diol has the ability to form hydrogen bonds and the capacity to separate structural isomers. Since most of its surface is covered with organic functions, the SiliaBond Diol absorbs less water, which leads to a more reproducible activity. It is also the sorbent of choice when working in normal phase in the presence of water. It has a different selectivity than bare silica gel and slight modifications in the composition of the solvent mixture may be necessary to obtain similar retention. In SPE, it is used for the isolation of drugs and metabolites from physiological fluids.
