Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 2-Ethylbenzo[d]oxazole, is researched, Molecular C9H9NO, CAS is 6797-13-3, about Novel and efficient heterogeneous polymer supported copper catalyst for synthesis of 2-substituted Benzoxazoles from 2-Haloanilides.Product Details of 6797-13-3.
A novel polymer supported copper complex was prepared by the immobilization of copper iodide on chem. modified polyacrylonitrile and its application in heterogeneous catalysis was described. The catalyst was prepared by easy method via synthetic modification of Polyacrylonitrile (PAN) using ethylene diamine followed by the complexation with CuI. After characterization, the complex was explored as a green and efficient heterogeneous catalyst for the synthesis of 2-benzoxazoles from 2-haloanilides. The reaction was performed without adding addnl. ligand and the catalyst shows activity over a broad range of substrates with quant. product yields. The catalyst was easily recovered by simple filtration and reused successfully for further cycle.
