SiliaBond® Piperazine
SiliaBond® Piperazine (Si-PPZ) is a useful deprotecting and scavenging agent for Fmoc1 and Bsmoc2 amino protecting groups and as a solid-phase Knoevenagel catalyst. According to the results of a study1, Si-PPZ is superior to its polystyrene-based equivalent. SiliaBond Piperazine may also be used to scavenge electrophiles.
-
SiliaBond® Tosyl Hydrazine
SiliaBond® Tosyl Hydrazine (Si-TsNHNH2) is an effective scavenger of carbonyl compounds. It has been used to selectively remove aldehydes in the presence of ketones since the scavenging of ketones requires an acid catalyst. Once bound, sulfonyl hydrazones can be utilized in other synthetic transformations.
-
SiliaBond® Piperidine
SiliaBond® Piperidine (Si-PIP) is a general purpose tertiary amine base to scavenge acids, thereby avoiding salt elimination problems. Also used as a base catalyst for Knoevenagel condensation.
-
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.
-
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.
