Chlorido[1-phenyl-3-(2,3,5,6-tetramethylbenzyl)benzimidazol-2-ylidene]silver(I)
In the title compound, [AgCl(C24H24N2)], the terminal phenyl and tetramethylbenzene rings [which form a dihedral angle of 87.92 (14)°] make dihedral angles of 59.59 (11) and 83.19 (12)° with respect to the central benzimidazole ring system. The Ag—C and Ag—Cl single-bond lengths are 2.087 (3) and 2.3267 (9) Å. The C—Ag—Cl bond angle is 172.84 (7)°. C—H⋯π interactions contribute to the stabilization of the crystal structure. A very weak π–π stacking interaction between adjacent tetramethylbenzene rings [centroid–centroid distance = 4.0610 (18) Å] is also observed

Çeşitli Aril Bromürler ile Heteroaromatiklerin Palladyum Katalizli Doğrudan C5 Arilasyonu için Yeni Pd-N-Heterosiklik Karben Komplekslerinin Sentezi ve Karakterizasyonu
Synthesis and characterization of 1-phenyl-3-alkylbenzimidazol-2-ylidene salts and their catalytic activities in the Heck and Suzuki cross-coupling reactions
The synthesis and characterization of 1-phenyl-3-alkyl-substituted carbene precursors that were prepared from 1-phenyl substituted benzimidazole and various alkyl halides are reported. The new benzimidazolium salts (1a-e) were characterized by H-1 NMR, C-13 NMR, FT-IR spectroscopic methods and elemental analyses. New in situ generated palladium-benzimidazolium complexes were tested for catalytic activity in the Mizoroki-Heck and Suzuki-Miyaura cross-coupling reactions
