Details

SiliaBond®  Guanidine is a silica-supported diisopropylguanidine ligand.

It is a very powerful scavenger for the chelating of organic acids in general, especially boronic acids
and phenolic acids.

It may also be used as a very strong base. It is sufficiently basic to deprotonate moderately acidic hydrogens,
as in the alkylation of amines and phenols (Williamson ether synthesis) and the esterification of carboxylic acids using alkyl halides.

It is also a new product that replaces SiliaBond TBD.
