POLYMER-SUPPORTED ALKYL AZODICARBOXYLATES AND THEIR USE IN MITSUNOBU REACTIONS

摘要

A process for preparing an azodicarboxylate composition by chemically bonding dialkyl azodicarboxylates onto an insoluble solid polymer support. This process comprises the immobilization of hydrazodicarboxylates onto an insoluble solid polymer support and oxidizing the hydrazodicarboxylates to azodicarboxylates. The azodicarboxylate-polymer composition may be used in Mitsunobu-type reactions. After use in Mitsunobu-type reactions, the azodicarboxylate-polymer composition is recoverable and may be reused.
