《Copper-mediated tandem ring-opening/cyclization reactions of cyclopropanols with aryldiazonium salts: synthesis of N-arylpyrazoles》 was published in Chemical Communications (Cambridge, United Kingdom) in 2020. These research results belong to Liu, Jidan; Xu, Erjie; Jiang, Jinyuan; Huang, Zeng; Zheng, Liyao; Liu, Zhao-Qing. Name: Methyl 4-fluorobenzoate The article mentions the following:
A general method for the synthesis of structurally diverse N-arylpyrazoles I [R = H, 3-Me, 4-Cl, etc.; R1 = c-Pr, Ph, 3-thienyl, etc.; R2 = H, Me, Et, etc.] from readily available cyclopropanols and aryldiazonium salts was disclosed. The reaction was conducted at room temperature within minutes with a broad substrate scope and excellent regioselectivity. In the experiment, the researchers used Methyl 4-fluorobenzoate(cas: 403-33-8Name: Methyl 4-fluorobenzoate)
Methyl 4-fluorobenzoate(cas: 403-33-8) is an organic fluorinated building block used for the synthesis of various pharmaceutical compounds. It can be used for the preparation of Blonanserin.Name: Methyl 4-fluorobenzoate
