Fred Capretta: Research Interests 

Molecular Hall of Fame

Thanks to Dr. C. S. Frampton of Roche Products, U.K. for the x-ray crystallographic analyses of the compounds below:
 
 
 
 
 

Dirhodium Tetra(dimethylphosphinate): Rhodium(II) carboxylates are the catalysts of choice for metal-stabilized carbene reactions.  Recent work in the Capretta lab has allowed for the replacement of the carboxylate ligands with isoelectronic phosphinates.  Pictured is a dirhodium catalyst containing four dimethylphosphinic acid ligands.
