The formed solid is purified by centrifugation, affording Co(nmp)2as a tan solid on a gram scale. The use of an aqueous solvent is crucial. Complexation in dry benzene produces a purple solid in a low yield that is less reactive than the tan‐colored Co(nmp)2. Pagenkopf and coworkers estimated that the actual structure of the catalyst contained adventitious water.1X‐ray analysis of Co(nmp)2crystals formed in chloroform indicated a water‐coordinated dimeric structure [Co(nmp)2]2·(H2O)2.2Handling, Storage, and Precautions:air stable.
