are efficient for a wide array of challenging C–C and C–X (X = heteroatom) cross-coupling reactions. Their high activity is correlated to their facile activation to a 12-electron-based “L-Pd(0)” catalystunder commonly employed conditions for cross-coupling reactions, noninhibitory byproduct release upon activation, and suppression of the off-cycle pathway to form dinuclear (μ-allyl)(μ-Cl)Pd2(L)2 species
