Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, European Journal of Organic Chemistry called Phospholane-Phosphite Ligands for Rh Catalyzed Enantioselective Conjugate Addition: Unusually Reactive Catalysts for Challenging Couplings, Author is Gilbert, Sophie H.; Fuentes, Jose A.; Cordes, David B.; Slawin, Alexandra M. Z.; Clarke, Matthew L., which mentions a compound: 36620-11-8, SMILESS is [F-][B+3]([F-])([F-])[F-].C12=C3[Rh+]14567(C8=C5C9C6=C7C8C9)C%10=C4C2CC3%10, Molecular C14H8BF4Rh, Application In Synthesis of Bis(norbornadiene)rhodium (I) tetrafluoroborate.
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
