The article was titled 《Synthesis and biological activities of artemisinin-piperazine-dithiocarbamate derivatives》. The information in the text is summarized as follows:

Twelve derivatives of artemisinin-piperazine-dithiocarbamate, I (R = CH2Ph, CH2C6H4Me-4, n-pentyl, CH2CO2CH2Ph, etc.), have been synthesized, and some of them show good in vitro cytotoxic activity. Compound I (R = CH2C6H4CN-4) (II) exhibits the best inhibitory activity against SMMC-7721 cell lines with an IC50 of 0.0025 ± 0.04 μM for 72 h, but the toxicity was lower against LO2 cell lines with an IC50 of 0.18 ± 0.04 μM for 72 h. The results indicate that compound II is more cytotoxic towards cancer cell lines than towards benign cell lines compared with vincristine in vitro. And compound II also has good inhibitory activity against colon, breast and prostate cancer cells.

The article was titled 《Cyanation of Anilines to Aryl Nitriles Using tert-Butyl Isocyanide: A Simple and Copper-free Procedure》. The information in the text is summarized as follows:

In this manuscript, a simple and copper-free procedure for the synthesis of aryl nitrile derivatives from anilines is described. Under the improved protocol, the anilines were reacted with tert-Bu isocyanide under a mild reaction condition without the use of solvents and copper catalyst to synthesize benzonitriles.

In addition, this method has afforded the aryl nitriles I (R1 = H, 4-Cl, 4-Me, 2-F, etc.) in moderate to good yields (52-81%). The obtained results in this study reveal that the tert-Bu isocyanide as a potential cyanide source for the cyanation reaction.

《Fluorination of arylboronic esters enabled by bismuth redox catalysis》 was published in Science (Washington, DC, United States) in 2020. These research results belong to Planas, Oriol; Wang, Feng; Leutzsch, Markus; Cornella, Josep. Synthetic Route of C7H4FN The article mentions the following:

Triarylbismuth complexes undergo oxidative addition to yield difluorobismuth(V) derivatives, which, upon the reductive elimination provide a valuable route for catalytic fluorination of organoboron compounds Bismuth catalysis has traditionally relied on the Lewis acidic properties of the element in a fixed oxidation state. In this paper, we report a series of bismuth complexes that can undergo oxidative addition, reductive elimination, and transmetalation in a manner akin to transition metals. Rational ligand optimization featuring a sulfoximine moiety produced an active catalyst for the fluorination of aryl boronic esters through a bismuth (III)/bismuth (V) redox cycle. Crystallog. characterization of the different bismuth species involved, together with a mechanistic investigation of the carbon-fluorine bond-forming event, identified the crucial features that were combined to implement the full catalytic cycle. In addition to this study using 4-Fluorobenzonitrile, there are many other studies that have used 4-Fluorobenzonitrile(cas: 1194-02-1Synthetic Route of C7H4FN) was used in this study.
