title: A homogeneous, recyclable rhodium(I) catalyst for the hydroarylation of Michael acceptors.
abstract: A robust and practical polymer-supported, recyclable biphephos rhodium(I) catalyst has been developed. Control of polymer molecular weight allowed the tuning of solubility such that the polymer-supported catalyst is soluble in nonpolar solvents and not soluble in polar solvents. Thus, catalytic addition of aryl- and vinylboronic acids to enones occurs under completely homogeneous conditions and catalyst recycle can be achieved by simple precipitation and filtration.
