Gilbert, Sophie H.; Fuentes, Jose A.; Cordes, David B.; Slawin, Alexandra M. Z.; Clarke, Matthew L. published the article 《Phospholane-Phosphite Ligands for Rh Catalyzed Enantioselective Conjugate Addition: Unusually Reactive Catalysts for Challenging Couplings》. Keywords: phospholane phosphite chiral ligand preparation; rhodium catalyst enantioselective conjugate addition unsaturated carbonyl arylboronic acid.They researched the compound: Bis(norbornadiene)rhodium (I) tetrafluoroborate( cas:36620-11-8 ).Name: Bis(norbornadiene)rhodium (I) tetrafluoroborate. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:36620-11-8) here.
The use of Rh catalysts derived from a phospholane-phosphite ligand were found to be more productive than the classic rhodium/BINAP system in enantioselective conjugate additions These catalysts enable the use of lower amounts of aryl boronic acid in an asym. arylation reaction that required an impractical excess of nucleophile. This catalyst was also found to enable the coupling of a poorly reactive Michael acceptor, N-CBz-2-3-dehydro-4-piperidone, or the coupling of poorly reactive 2-furyl boronic acids at ambient or near temperatures
The article 《Phospholane-Phosphite Ligands for Rh Catalyzed Enantioselective Conjugate Addition: Unusually Reactive Catalysts for Challenging Couplings》 also mentions many details about this compound(36620-11-8)Name: Bis(norbornadiene)rhodium (I) tetrafluoroborate, you can pay attention to it, because details determine success or failure
