In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called A rhodium-catalyzed Sonogashira-type coupling exploiting C-S functionalization: orthogonality with palladium-catalyzed variants, published in 2019, which mentions a compound: 36620-11-8, Name is Bis(norbornadiene)rhodium (I) tetrafluoroborate, Molecular C14H8BF4Rh, Synthetic Route of C14H8BF4Rh.
This report concerns the development of an efficient Sonogashira-type coupling of arylmethylsulfides and terminal alkynes to generate aryl alkyne motifs. Orthogonal reactivity between traditional Pd catalysts, and the Rh catalysts employed, results in the ability to selectively activate either the C-S bond or C-X bond through catalyst choice. The Rh-bisphosphine catalyst has further been shown to be able to effect a hydroacylation-Sonogashira tandem sequence, and in combination with further onward reactions has been used in the synthesis of heterocycles and polycyclic systems.
Although many compounds look similar to this compound(36620-11-8)Synthetic Route of C14H8BF4Rh, numerous studies have shown that this compound(SMILES:[F-][B+3]([F-])([F-])[F-].C12=C3[Rh+]14567(C8=C5C9C6=C7C8C9)C%10=C4C2CC3%10), has unique advantages.
