4. Scavenging Palladium Catalysts

A metal scavenging study using SiliaBond® Metal Scavengers products was conducted on various palladium catalysts (Pd(OAc)2, Pd(allyl)2Cl2, Pd2(dba)3, Pd(PPh3)4) commonly used in organic synthesis.

Various parameters were studied for their influence on the scavengers' robustness as well as to establish the best conditions to bring the level of metal down to an acceptable level for the pharmaceutical industry (i.e.: solvent, number of equivalents, temperature, and reaction time).

  1. SiliaBond® Amine

    SiliaBond® Amine

    SiliaBond® Amine (Si-NH2) is an effective scavenger of acid chlorides, sulfonyl chlorides, isocyanates and other electrophiles. Si-NH2 has been shown to be effective metal scavenger and catalyst for Knoevenagel reactions. SiliaBond Amine is also used in chromatography as normal phase sorbent.

  2. SiliaMetS® Diamine

    SiliaMetS® Diamine

    SiliaMetS® Diamine (Si-DIA) is a proven scavenger for metals and electrophiles. It scavenges acids, acid chlorides, anhydrides, aldehydes, isocyanates, and chloroformates as well as Pb, Ni, and Cd.

  3. SiliaMetS® Triamine

    SiliaMetS® Triamine

    SiliaMetS® Triamine (SiliaMetS WAX-3, Si-TRI) is effective for scavenging metals such as Pb, Co, Ru and Pd. Our screening studies have shown it to be the preferred scavenger for Pb. It can also be used as a scavenger for acid chlorides, isocyanates and other electrophiles.
