Abstract
| - Reaction of the xylene-bridged bisbenzimidazolium salts 2,6-bis(N-alkyl-N‘-methylenebenzimidazolium)-1-bromophenylene dibromide (1, alkyl = ethyl; 2, alkyl = n-propyl; 3, alkyl = n-butyl) with [Pd2(dba)3]yields the palladium pincer complexes of type [Pd(L)Br], 4−6 (L = 2,6-bis(N-alkyl-N‘-methylenebenzimidazolin-2-ylidene)phenylene). Pincer complexes 4−6 have been tested as precatalysts in Heck andSuzuki coupling reactions of various aryl bromides with styrene and phenylboronic acid, respectively.
- Pincer-type palladium complexes derived from xylene-bridged bis(benzimidazolin-2-ylidene) donors have been synthesized and tested in catalytic C−C coupling reactions.
