Super paramagnetic CuFe2O4 November 1 2018 was used as an efficient catalyst for green formylation of structurally diverse alcohols to the Accepted November 1 2018 corresponding formyl esters using formic acid as a solvent 60-70 C . All reactions were Available online carried out successfully within 1-120 min to afford the products in 76-96 yields. Reusibility November 1 2018 of CuFe2O4 MNPs was examined 5 times without significant loss of its catalytic activity. Keywords Alcohols CuFe2O4 Formylation Nanoparticles Super paramagnetic 2018 by the authors licensee Growing Science Canada. 1. Introduction Functional group protection has a crucial role in the synthesis of different kind of organic and pharmaceutical Among the various protecting groups used for the hydroxyl function formylation is one of the most common protecting methods because of easy and fast formation of formate and it s deprotection under mild 3 The development of heterogeneous reagents has become a main part of research in industry and in developing technologies because the reactions are carried out under mild conditions and the target molecules are easily .
