Dabco as an Inexpensive and Highly Efficient Ligand for Palladium-Catalyzed Suzuki−Miyaura Cross-Coupling Reaction LiJin-Heng LiuWen-Jie 2004 An inexpensive and highly efficient Pd(OAc)<sub>2</sub>/Dabco catalytic system has been developed for the cross-coupling of aryl halides with arylboronic acids. A combination of Pd(OAc)<sub>2</sub> and Dabco (triethylenediamine) was observed to form an excellent catalyst, which affords high TONs (turnover numbers; TONs up to 950 000 for the reaction of PhI and <i>p</i>-chlorophenylboronic acid) for Suzuki−Miyaura cross-coupling of various aryl iodides and bromides with arylboronic acids.
