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 Synthesis and characterization of new fluorescent triarylborane polymers, published in 2005, which mentions a compound: 75732-01-3, Name is Mesitylcopper(I), Molecular C9H11Cu, HPLC of Formula: 75732-01-3.
Organotin and organocopper compounds were applied as highly aryl-transfer reagents in the post-polymerization modification of poly(4-dibromoborylstyrene). The following aryl-transfer agents were studied: 2-thienyltrimethyltin, mesitylcopper, and 5-hexyl-5′-trimethylstannyl-2,2′-bithiophene. Depending on the introduced aryl moiety, the resulting boron-modified polystyrenes may reversibly bind to external electron donor species and hence may act as fluorescent sensors.
In addition to the literature in the link below, there is a lot of literature about this compound(Mesitylcopper(I))HPLC of Formula: 75732-01-3, illustrating the importance and wide applicability of this compound(75732-01-3).
