A variety of chiral and achiral imidazolium salts is synthesized. Methylene-, ethylene-, propylene- and pyridinyl-bridged bis(imidazolium) halides are used to generate the respective free chelating carbenes. The synthesis of palladium complexes of general formula [cis-CH2{NC(H)=C(H)N(R)C} 2PdX2] with these chelating N-heterocyclic carbene ligands is reported. Structural proofs of complexes 28 and 46 are represented by X-ray diffraction studies. Catalytic applications in the Mizoroki-Heck reaction are presented. Georg Thieme Verlag Stuttgart.

King of donor: The chelating bis(carbene) 1 enabled the synthesis of the new silyliumylidene salt 2. This salt can be dechlorinated with sodium naphthalenide to give the first cyclic siladicarbene 3, which bears a single Si0 atom with strikingl

A method for the synthesis and isolation of 1,1′-methylene-bis-(3- aryl-imidazol-2-ylidene) ligands, aryl = 2,6-diisopropyl-phenyl (DiPP), L DiPP, mesityl (mes), Lmes, is reported, which provides synthetically useful quantities of hi
