Abstract

Abstract: A new functionalized N‐heterocyclic carbene Pd II complex, [1, 1′‐(hexylene‐1, 6‐diyl)bis(3‐ n ‐butylbenzimidazol‐2‐ylidene)][PdCl2 (CH3 CN)]2 (2 ) has been synthesized by reaction of NHC‐Ag transmetalation reagent with PdCl2 (CH3 CN)2 . The molecular structure of2 adopts an open conformation. Complex2 was tested as a catalyst for Suzuki–Miyaura couplings of aryl halides with arylboronic acids in water and air. The results of these efforts show that2 is an efficient precatalyst for such reactions. In addition, 2 is a good catalyst in Heck–Mizoroki reactions of aryl bromides with styrene. Abstract : A new 1, 6‐hexylene‐bridged bis‐N‐heterocyclic carbene Pd II complex was prepared and characterized. The catalytic activities of this complex in Suzuki–Miyaura and Heck–Mizoroki reactions were investigated.
