Solvent-free isomerization of allylic alcohols catalyzed by a rhodium catalyst-organic framework

The solvent-free isomerization of allylic alcohols is reported using an immobilized rhodium catalyst-organic framework (COF) synthesized from alternating ring-opening metathesis polymerization (altROMP) assembly. The catalyst provided TONs as high as 38 000, with catalyst loadings as low as 0.0025 mol% for the isomerizations. Kinetic resolution of starting allylic alcohol 5 was also observed.
