Zhang, Yu published the artcileA new tetraphosphine and its application in Pd-catalyzed Suzuki cross-coupling reaction, Recommanded Product: 5-Nitro-2-phenylpyridine, the publication is Youji Huaxue (2012), 32(4), 790-793, database is CAplus.
A new tetraphosphine, N,N,N’,N’-tetra(diphenylphosphinomethyl)-cyclohexane-1,2-diamine has been designed and synthesized from the com. available cyclohexane-1,2-diamine as starting material. This tetraphosphine in combination with [Pd(η3-C3H5)Cl]2 is a very efficient catalyst for Suzuki cross-coupling reaction. Various aryl and heteroaryl chlorides or bromides could be successfully transformed to the desired products in up to 99% yield with 0.1 mol% catalyst loading.
Youji Huaxue published new progress about 89076-64-2. 89076-64-2 belongs to pyridine-derivatives, auxiliary class Pyridine,Nitro Compound,Benzene, name is 5-Nitro-2-phenylpyridine, and the molecular formula is C7H7ClN2S, Recommanded Product: 5-Nitro-2-phenylpyridine.
