Abstract: A method for enhancing the purity of a desired compound comprising:
Step (a) treating a crude reaction product which contains at least one desired compound, unreacted starting materials and/or byproducts with at least one bifunctional quenching agent that is capable of selective covalent reaction with unwanted byproducts, or excess reagents;
Step (b) allowing the quenching agent to covalently react with unreacted starting materials and/or byproducts to afford a derivatized compound of the quenching agent: and
Step (c) isolating the desired compound is described as well as novel quenching agents and methods for their use in the rapid purification of synthetic intermediates and products in synthesis, combinatorial chemistry, and automated organic synthesis.

Abstract: Process for producing a secondary amine terminated polyether from a primary amine terminated polyether in which the primary amine terminated polyether is reacted at elevated temperature with a carbonyl compound in the presence of hydrogen and a catalyst composition comprising nickel, ruthenium and at least one other transition metal selected from the second or third row transition metals. The amount of carbonyl compound employed is in excess of the stoichiometric amount required to react completely with the ether. The secondary amine terminated polyethers are useful in the formation of polyurea elastomers.
