Solvent-free Ugi Four-component Synthesis and Insecticidal Activities of Novel Fluorine-Containing Philanthotoxins-12 Derivatives

Chinese Journal of Applied Chemistry (2009)

Nian-Jin LIU Song Cao Yan-Ming MA Li Shen Xu-Hong QIAN

Eight novel fluorine-containing PhTX-12 derivatives were prepared under one-pot Ugi four-component solvent-free conditions, followed by the simple removal of the protecting groups in the presence of trifluoroacetic acid. Their structures were identified by 1H NMR, 13C NMR and HRMS. Preliminary bioassays indicated that compound 6b showed 44% and 42% mortality rate against Heliothis armigera and Pieris rapae at a concentration of 100 mg/L.

Transition-Metal-Free Sonogashira-Type Cross-Coupling of Alkynes with Fluoroarenes

Organic Letters (2013)

Guanyi Jin Xuxue Zhang Song Cao

A novel, inexpensive, and efficient palladium-, copper-, ligand-, and amine-free Sonogashira-type cross-coupling reaction of terminal alkynes with unreactive aryl fluorides in the presence of sodium, sodium methoxide, and calcium hydroxide under the assistance of a Grignard reagent was developed. A plausible mechanism was also suggested.

Scientific Communities Found Based on the Path Structure of Citation Network

International Journal of Intelligence Science (2012)

Xiao Xiao Song Cao Lan Huang Yutian Tang

Based on the structure of citation network, the citation paths among papers, and the association strength such as coupling, co-citation and etc. between two papers are defined in this article. We give formulas to quantify the association strength in order to establish citation network model based on the citation path structure. Then, the OPTICS algorithm is brought into the scientific communities found model since it can solve the parameter’s setting problem. This method combines various kinds of path structures together and thus it contains more complete citation network information. Experiments and analysis reveal the reliability and validity of this method.

Fe-catalyzed hydroxytrifluoromethylation of α-(trifluoromethyl)styrenes with CF₃SO₂Na: facile access to α,β-bistrifluoromethyl tertiary alcohols

Organic & Biomolecular Chemistry (2022)

Pai Zheng Chuan Liu Qianding Zeng Yi Zhang Ying Liu

A mild and practical Fe-catalyzed hydroxytrifluoromethylation of α-(trifluoromethyl)styrenes with CF3SO2Na in the presence of K2S2O8 and air was developed. The reaction proceeded efficiently at room temperature without β-fluoride elimination and afforded the corresponding α,β-bistrifluoromethyl tertiary alcohols in good to excellent yields.
