Sequential Reactions with Grubbs Catalyst and AD-mix-α/β Using PDMS Thimbles
摘要:
Incompatible Grubbs catalyst and an osmium dihydroxylation catalyst were site-isolated from each other using polydimethylsiloxane thimbles. The Grubbs catalyst was added to the interior of the thimbles, and AD-mix-alpha/beta was added to the exterior. Organic substrates readily fluxed through the walls of the thimbles and reacted with each catalyst. A series of cascade reactions were developed including those with Intermediates possessing low boiling points or that were foul smelling.
