Özet
Abstract Novel palladium‐1,3‐dialkylperhydrobenzimidazolin‐2‐ylidene (2a–c) and palladium‐1,3‐dialkylimidazolin‐2‐ylidene complexes (4a,b) have been prepared and characterized by C, H, N analysis, 1H‐NMR and 13C‐NMR. Styrene or phenylboronic acid reacts with aryl halide derivatives in the presence of catalytic amounts of the new palladium‐carbene complexes, PdCl2(1,3‐dialkylperhydrobenzimidazolin‐2‐ylidene) or PdCl2(1,3‐dialkylimidazolin‐2‐ylidene) to give the corresponding CC coupling products in good yields.
