Abstract
A method of using a reaction plenum in the presence or absence of paramagnetic beads to perform chemical syntheses resulting in separation and recovery of a final desired reaction product is provided. The reaction plenum comprises a reaction plate, a reaction vessel for mounting in the reaction plate, a reaction plate holder, a screw-like rod, a mounting block attached to the reaction plate holder for operably receiving the screw-like rod, a motor, a sonication region in a temperature controllable water bath and a magnetic separation region in the water bath. Paramagnetic beads having reaction sites are introduced into the reaction vessels along with the appropriate solvent and one or more reactants. The contents of the reaction vessel are sonicated, then moved to the magnetic separation region where the paramagnetic beads are tightly held against the reaction vessel while the solvent is aspirated off. Once the desired reaction product is attained, the reaction product is cleaved off the paramagnetic bead. In an alternative embodiment, chemical synthesis is performed in a similar manner in the absence of the paramagnetic beads.
