Pd-PEPPSI-IHeptCl, a new, very bulky yet flexible Pd-NHC complex was evaluated in the Negishi coupling of secondary alkylzinc reactants with a wide variety of oxidative addition partners in high yields and excellent selectivity. The desired, direct reductive elimination branched products I [Ar = 2-pyridyl, 5-indolyl, 3-benzo[b]thiophenyl, etc.], II and e.g., III, were obtained with no sign of migratory insertion across electron-rich and electron poor aromatics and all forms of heteroaromatics (5- and 6-membered). Impressively, there was no impact of substituents at the site of reductive elimination (i.e., ortho or even di-ortho), which was not yet been demonstrated by another catalyst system to date.
