COA of Formula: C30H21P. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: Tri(naphthalen-1-yl)phosphine, is researched, Molecular C30H21P, CAS is 3411-48-1, about Tri(1-naphthyl)phosphine as a ligand in palladium-free Sonogashira cross-coupling of arylhalogenides with acetylenes. Author is Govdi, Anastasiya I.; Vasilevsky, Sergey F.; Malysheva, Svetlana F.; Kazheva, Olga N.; Dyachenko, Oleg A.; Kuimov, Vladimir A..
Tri(1-naphthyl)phosphine (Np3P) was easily prepared in 34% yield from red phosphorus and 1-bromonaphthalene in superbasic system t-BuONa/DMSO. The expedient procedure for the synthesis of diaryl acetylenes ArC≡CAr1 [Ar = Ph, 4-MeOC6H4, 2-O2NC6H4, etc.; Ar1 = Ph, 4-MeC6H4, 4-BrC6H4, etc.] by Sonogashira coupling of aryl iodides with terminal alkynes using Np3P as a ligand was developed. For the first time, it was found that the reaction with compounds containing electron-donating substituents preferably afforded buta-1,3-diynes ArC≡C-C≡CAr1.
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.
