Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:221012-82-4) through the article.
The Ni-catalyzed cyclization of bisphosphine derivatives to form various phosphacycles is reported. The reaction proceeds via the cleavage of two C-P bonds of the bisphosphine. Unlike the previously reported Pd catalysts, the use of Ni as a catalyst allows for the cyclization that requires C(alkyl)-P bond cleavage. A phospha-nickelacycle intermediate was successfully isolated and characterized by x-ray crystallog.
Although many compounds look similar to this compound(221012-82-4)Quality Control of (R)-2,2′,6,6′-Tetramethoxy-4,4′-bis(diphenylphosphino)-3,3′-bipyridine, numerous studies have shown that this compound(SMILES:COC(C=C1P(C2=CC=CC=C2)C3=CC=CC=C3)=NC(OC)=C1C4=C(OC)N=C(OC)C=C4P(C5=CC=CC=C5)C6=CC=CC=C6), has unique advantages.
