A general palladium-catalyzed cross-coupling of aryl fluorides and organotitanium (IV) reagents was written by He, Xiao-Yun. And the article was included in Monatshefte fuer Chemie in 2021.Reference of 383-31-3 This article mentions the following:
Pd(OAc)2/1-[2-(di-tert-butylphosphanyl)phenyl]-4-methoxy-piperidine was demonstrated to effectively catalyze cross-coupling of aryl fluoride and aryl(alkyl) titanium reagent. Both electron-deficient and electron-rich aryl fluoride reacted effectively with nucleophile and provided extensive functional groups tolerance. 2-Arylated product was realized by selective activation of the C-F bond. In the experiment, the researchers used many compounds, for example, 4-Fluoro-N,N-dimethylbenzenesulfonamide (cas: 383-31-3Reference of 383-31-3).
4-Fluoro-N,N-dimethylbenzenesulfonamide (cas: 383-31-3) belongs to amides. Amides are pervasive in nature and technology. Proteins and important plastics like Nylons, Aramid, Twaron, and Kevlar are polymers whose units are connected by amide groups (polyamides); these linkages are easily formed, confer structural rigidity, and resist hydrolysis. The presence of the amide group –C(=O)N– is generally easily established, at least in small molecules. It can be distinguished from nitro and cyano groups in IR spectra. Amides exhibit a moderately intense νCO band near 1650 cm−1. By 1H NMR spectroscopy, CONHR signals occur at low fields. In X-ray crystallography, the C(=O)N center together with the three immediately adjacent atoms characteristically define a plane.Reference of 383-31-3
