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 Visible-light photocatalytic preparation of alkenyl thioethers from 1,2,3-thiadiazoles and Hantzsch esters: synthetic and mechanistic investigations, published in 2021, which mentions a compound: 60804-74-2, Name is Tris(2,2′-bipyridine)ruthenium bis(hexafluorophosphate), Molecular C30H24F12N6P2Ru, Computed Properties of C30H24F12N6P2Ru.
A protocol to synthesize trisubstituted alkenyl thioethers I (R1 = Ph, 3-ClC6H4, 2-naphthyl, 2-thienyl, etc.; R2 = i-Pr, cyclohexyl, PhCH2, PhCMe2, etc.) through a direct S-alkylation of 1,2,3-thiadiazoles II with C-radical precursors, 4-alkyl-1,4-dihydropyridines III (R3 = EtO2C, t-BuO2C, CN), driven by visible-light photocatalysis is disclosed. A broad range of primary, secondary and tertiary C-radical precursors is suitable for this reaction and the desired products can be obtained in good to excellent yields under mild conditions. Remarkably, high stereoselectivity with Z-alkenyl thioethers was achieved in the presence of a Cu(OAc)2 catalyst. Synergistic exptl. and computational studies were carried out to shed light on the mechanisms of this reaction, in which the quenching pathway of an excited photocatalyst (*RuII) could be altered in the presence of the Cu(OAc)2 catalyst. A reductive quenching pathway (RuII/*RuII/RuI/RuII) was proposed in the absence of the Cu(OAc)2 catalyst while an oxidative quenching pathway (RuII/*RuII/RuIII/RuII) was suggested with the assistance of the Cu(OAc)2 catalyst. In addition, the origin of the Z-selectivity of the product was discussed.
Although many compounds look similar to this compound(60804-74-2)Computed Properties of C30H24F12N6P2Ru, numerous studies have shown that this compound(SMILES:F[P-](F)(F)(F)(F)F.F[P-](F)(F)(F)(F)F.C1(C2=NC=CC=C2)=NC=CC=C1.C3(C4=NC=CC=C4)=NC=CC=C3.C5(C6=NC=CC=C6)=NC=CC=C5.[Ru+2]), has unique advantages.
