Abstract

The cluster complex Cp₃Co₃(CO)₂ (1) undergoes a unique, solvent-induced, two-step fragmentation reaction to give the di- and tetranuclear complexes Cp₂-Co₂(CO)₂ (2) and Cp₄Co₄(CO)₂ (3). The mechanism of this reaction is shown to involve initial, reversible attack of solvent (benzene or THF) on 1, causing fragmentation to 2 and a solvated, mononuclear intermediate, CpCo-(sol)_n. This intermediate subsequently reacts with a second molecule of 1 to form 3. The mononuclear species shows a surprising selectivity in its reactions with trapping agents depending upon the nature of the coordinated solvent.
