Abstract: | Abstract Monomeric Mn2+, Co2+ and Ni2+ complexes of tris(2-pyridyl)phosphine (P(2-py)3 were synthesized through the reaction of the hydrated metal(II) chlorides with P(2-py)3 in near-quantitative yields. The solid-state structure of the Mn complex was determined by single-crystal X-ray diffraction.
All three complexes were tested as homogeneous catalysts for the oxidation of tetralin to α-tetralone with tert-butyl hydroperoxide (TBHP) as oxidant. The influences of temperature, solvent, catalyst molar ratio and time of the reaction
on the catalyzed reactions were investigated. |
