SiliaBond Reagents & Oxidants for Michael Addition

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.
