WebMar 23, 2024 · In the present study, we report the synthesis of a series of copper(II) complexes with a wide range of ligands and their testing in the copper catalyzed Chan-Evans-Lam (CEL) coupling of aniline and phenylboronic acid. The efficiency of the coupling was directly connected with the ease of the reduction of Cu(II) to Cu(I) of the complexes. WebSep 17, 2024 · The Chan-Evans-Lam reaction of 1-unsubstituted 4-fluoroalkylpyrimidin-2(1Н)-ones with arylboronic acids is reported as a facile synthetic route to hitherto unavailable N1-(het)aryl and N1-alkenyl derivatives of the corresponding pyrimidines.An efficient C-N bond-forming process is also observed by using boronic acid pinacol esters …
