Treatment of 1‐(n‐butyl)‐3‐N‐(2‐Ar)acetamido‐1, 3‐imidazolium chloride (Ar=furylmethyl,phenylmethyl) with excess K2CO3 and [PdCl2(L−L)] (L−L=2 PPh3, dppf) afforded orange compounds of composition [(1‐(n‐butyl)‐3‐N‐(2‐Ar)acetamido‐1,3‐imidazol‐2‐ylidene)]2Pd (Ar=furylmethyl; phenylmethyl). These complexes were characterized by NMR (1H and 13C{1H} NMR), IR and micro‐analysis data. Subsequently, the catalytic efficiency of these complexes for cross coupling reactions between 4‐haloarenens (halo=Br, I) and phenylboronic acid was studied under different solvents (acetonitrile, THF and DMF), temperatures with different catalyst loadings. The molecular structure of [(1‐(n‐butyl)‐3‐N‐(2‐furylmethyl)acetamido‐1, 3‐imidazol‐2‐ylidene)]2Pd was established by single crystal X‐ray diffraction analysis. [ABSTRACT FROM AUTHOR]
