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 Electron spin resonance studies of the reactions of tri(1-naphthyl)phosphine and its oxide, sulfide, and selenide with alkali metals in tetrahydrofuran and 1,2-dimethoxyethane, published in 1970, which mentions a compound: 3411-48-1, Name is Tri(naphthalen-1-yl)phosphine, Molecular C30H21P, COA of Formula: C30H21P.
Tri(1-naphthyl)phosphine (I) was treated sep. with Li, Na, K, and Na-K alloy in tetrahydrofuran (THF) and in 1,2-dimethoxyethane (DME). In both solvents, the reaction of I with Na gave the naphthalene radical anion (II) while with K (•C10H7)2PK%- (II) was formed. Reduction with Na-K alloy gave a mixture of II and III. The reaction of I with Li gave the 1,1′-binaphthyl radical anion, but when the Li was allowed to react initially with glass and then with I, the perylene radical anion was formed. The oxide, sulfide, and selenide derivatives of I all behaved similarly to I in their reactions with the alkali metals in THF and DME. The ESR spectra of the 1,1′-binaphthyl radical anion were also studied.
In some applications, this compound(3411-48-1)COA of Formula: C30H21P is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
