WebA general cobalt-catalyzed cross-coupling between alkyl iodides and cyclopropyl, cyclobutyl, and alkenyl Grignard reagents enables an introduction of strained rings on a large panel of primary and secondary alkyl iodides. The catalytic system is simple and nonexpensive, and the reaction is chemoselective and diastereoconvergent. WebMar 15, 2024 · A wide variety of boronic acids and esters, each with different properties, have been developed for this process. Despite the popularity of the Suzuki–Miyaura reaction, the precise manner in which the organic fragment is transferred from boron to palladium has remained elusive for these reagents.
