[摘要]：Resin immobilized stable, spherical CuO nanoparticles prepd. in the presence of cyclodextrin (CD) act as catalysts for liq. phase alc. oxidn. in air. The catalytic activity of the CuO nanocomposites and its green chem. approach make it superior to the related resin-bound Cu(0) nanocomposite. The effect of alc. chain length and electron-donating or -withdrawing groups influence product yield. The nanocomposites exhibit good reusability, simple workup procedure, and a straightforward approach to aldehyde formation.
