Ligand-Controlled Regiodivergent Hydroalkylation of Pyrrolines was written by Qian, Deyun;Hu, Xile. And the article was included in Angewandte Chemie, International Edition in 2019.Quality Control of 1-Chloro-4-iodobutane This article mentions the following:
Two series of C-alkylated pyrrolidines I [R = Boc, Cbz; R1 = i-Pr, cyclopentyl, indol-1-yl, etc.] and II [R2 = CO2Ph, Boc, Cbz; R3 = cyclohexyl, (CH2)3Ph, 2-thienyl, etc.] were synthesized via ligand controlled nickel-catalyzed regiodivergent hydroalkylation of 3-pyrrolines with alkyl/aryl halides. This method demonstrated broad scope and high functional-group tolerance and could be applied in late-stage functionalizations. In the experiment, the researchers used many compounds, for example, 1-Chloro-4-iodobutane (cas: 10297-05-9Quality Control of 1-Chloro-4-iodobutane).
1-Chloro-4-iodobutane (cas: 10297-05-9) belongs to iodide derivatives. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. Organoiodine lubricants can be used with titanium, stainless steels, and other metals which tend to seize up with conventional lubricants: organoiodine lubricants can be used in turbines and spacecraft, and as a cutting oil in machining.Quality Control of 1-Chloro-4-iodobutane
