Preparation and intramolecular metal-exchange reaction of cationic trinuclear µ3-η3-(C,C,O)-ketene complexes
Abstract
Co-ordination of the acyl oxygen atom in a di-iron µ2-η2-(C,C)-ketene complex, Fp–CH2CO–Fp [Fp =(η5-C5H5)Fe(CO)2] to Lewis acidic organometallic centres produces cationic trinuclear µ3-η3-(C,C,O)-ketene complexes, the two metal components of which exchange with each other via an intramolecular process.
