Cu(acac)(2) immobilized in ionic liquids: A reusable catalytic system for the insertion of alpha-diazo compounds into N-H bonds of amines

Kantam ML, Neelima B, Reddy CV

Copper(II) acetylacetonate (Cu(acac)Z) immobilized in ionic liquids (ILs) catalyzes the insertion of alpha-diazoacetate into N-H bonds of amines to afford glycine esters in good yields under ambient conditions. The use of ionic liquid allows easy separation of the product and recycling of copper catalyst. (c) 2006 Elsevier B.V. All rights reserved.
