Affordable iron catalysts offer sustainable route to valuable Z-alkenes
This schematic illustrates the development of an iron-catalyzed dialkylation reaction that selectively converts arenes to the thermodynamically unfavorable Z isomer of trisubstituted alkenes. The reaction proceeds through transition states TS 1 and TS 2, each involving a different carbon-carbon bond formation chemical process. The high regioselectivity and Z-selectivity of this method make it a valuable tool for organic synthesis. Credit:…
