Good donor ligands react with an sp(2) cyclometalated complex of platinum containing an agostic interaction, initially causing displacement of the agostic interaction and decyclometalation. Eventually, these complexes rearrange to give sterically less congested complexes containing an sp(3) cydometalated group. The same end products are observed even with poor donor ligands that do not displace the agostic interaction, and this, together with other results, suggests to us that the route to the end products goes via a different agostic species. These sp(3) cyclometalated complexes can be made to dicyclometalate via the simple expedient of adding water/base. Finally, dissolution of the agostic complex in DMSO results in a reversible rollover reaction, giving a C(Lambda)C chelated ligand.
