Heck reaction: Pd-catalyzed alkene arylation
0 arrows drawnStep 1 of 3: Oxidative addition
Palladium(0) inserts into an aryl-bromide bond, an alkene then inserts into the resulting Pd-Ar bond, and the new alkyl-Pd species loses a beta-hydride to give a styrene-type product. Three pages of the textbook catalytic cycle, with the base-mediated Pd regeneration step skipped for V3.
Click an atom to start an arrow from a lone pair, or click a bond to start an arrow from that bond. Then click the atom or bond where the electrons land. Atoms are numbered by their position in the SMILES string. Keyboard: Tab to cycle focus, Enter to commit, Esc to cancel. Drag the small handle on a drawn arrow to sculpt the curve; double-click to reset.
