AI Article Synopsis
- Researchers have characterized the first rhodium eta(1)-allyl complexes, revealing new insights into their structure.
- The study demonstrates that the sigma-bound allyl group can quickly transfer from a Rh(III) complex to a Rh(I) complex through a rapid equilibrium process.
- This transfer mechanism may explain the decreased regioselectivity seen in certain allylic alkylation reactions when using complex 1 as a catalyst.
Article Abstract
Metal-to-metal allyl transfer: Using the first structurally characterized rhodium eta(1)-allyl complexes it is shown that the sigma-bound allyl substituent can be transferred from the Rh(III) complex to a Rh(I) complex in a fast equilibrium. This process may account for the decrease in regioselectivity observed in allylic alkylation reactions in which complex 1 is used as a catalyst.
