Abstract
A specific example of a Sequestration Enabling Reagent (SER), tetraflu orophthalic anhydride, is used in the purification of solution-phase r eactions involving amines with electrophiles. The SER is added to an i ncomplete reaction mixture containing product, amine, and electrophile . The SER covalently reacts with remaining amine, affording a derivati zed amine with an artificially-imparted acid rag. This ''tagged'' amin e is now sequesterable by the same CMR/R polyamine resin used to seque ster the electrophile and both are easily removed from the reaction mi xture affording pure product.
