Homogenous liquid phase oxygenation of 1-tetralin using α-diimine palladium(ii) complexe

Abstract

This work describes the homogeneous liquid phase oxygenation of 1-tetralin catalyzed by a-diimine Pd(II) complexes (a -diimine: ArN=C(R)C(R)=NAr (Ar = p -C 2 H 5 C 6 H 4, 2-iPrC 6 H 5, C 6 H 5 and R = Me, Ph, acetanaphtalenyl). Carrying out the reaction at T = 120°C, P air = 5.4 atm, a substrate/catalyst ratio = 100 for 3 h, this substrate is converted to the corresponding 1-tetralone and 1-tetralol products.
