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.
