HPLC of Formula: 58656-04-5. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: Tricyclohexylphosphonium tetrafluoroborate, is researched, Molecular C18H34BF4P, CAS is 58656-04-5, about Efficient and Practical Synthesis of 3′,4′,5′-Trifluoro-[1,1′-biphenyl]-2-amine: A Key Intermediate of Fluxapyroxad. Author is Li, Zhenhua; Zhang, Xuchao; Qin, Jinjing; Tan, Zhiyong; Han, Meizhen; Jin, Guoqiang.
An improved and practical method is reported here for accessing 3′,4′,5′-trifluoro-[1,1′-biphenyl]-2-amine, a key intermediate for Fluxapyroxad. The overall yield for the preparation was 73%, with a purity of 99.88%, after a three-step process. More importantly, this process was an improvement in the manufacture of biphenyl compounds by Suzuki-Miyaura coupling, which enabled catalyst loading as low as 0.04 mol %. This method could provide an economic and environment-friendly process leading to extensive prospects in industrial applications.
