Abstract

Abstract The facile synthesis of polyethylene glycol (PEG)-immobilized iron (II) porphyrin using a copper-catalyzed azide-alkyne [3+ 2] cycloaddition “click” reaction is reported. The prepared complex 5 (PEG-C 51 H 39 FeN 7 O) was found to be an efficient catalyst for the selective olefination of aldehydes with ethyl diazoacetate in the presence of triphenylphosphine, and afforded excellent olefin yields with high (E) selectivities. The ...
