We're incredibly proud to say that our review of Cross-Electrophile Coupling: Principles, Methods, and Applications in Synthesis is now online and open access at @ACSChemRev! Congrats to the team for this labor of love (and data!)

The wide variety of organic additives used means that TMSCl represents the largest portion with only 12% of all organic additives used. Silane reagents like TMSCl can activate metal powder reductants or by playing a direct role in the reaction mechanism.

While Zn salts can be generated in situ over the course of an XEC reaction, alkali and alkaline earth metal salts predominate by one to two orders of magnitude over other salt additives. Among all salt additives, Mg Salts (eg. MgCl2 and MgBr2) are the most common (27%)

While Csp2-Csp3 bonds do make up 55% of all XEC publications reported, the remaining 45% is comprised of a wide variety of other coupling types, from Csp2-Csp2 and Csp3-Csp3 to alkene and alkyne difunctionalization, among many others!

Across single- and mixed-solvent systems, non-amide solvents are used in about 30% of all XEC reports! DMA and DMF, in comparison, represent 50% of all solvents used.

XEC catalysis is dominated by the 3d transition metals, and nickel is far and away the most-used catalyst (88% of reports!) and no other metal is more than 3%.
