Bis(3- salicylideneaminopropyl)aminecobalt(II)

Bis(3-salicylideneaminopropyl)aminecobalt(II) is a catalyst for the homogeneous oxygenation of phenols with dioxygen in organic media.

Bis(3-salicylideneaminopropyl)aminecobalt(II) is prepared under nitrogen from bis(salicylaldehydehydato)cobalt(II) dihydrate and bis(3- aminopropyl)amine. The long green prisms are collected by suction, washed with cold methanol, and dried in a vacuum desiccator. May be recrystallized from methanol if necessary; normally used without further purification.
