摘要

A new thiophene-functionalized benzimidazolium salt (2) has been prepared by reacting N- methylbenzimidazole with 2-bromomethylthiophene (1), which in turn was obtained by bromination of 2-thiophenemethanol with PBr3. Subsequent reaction of salt 2 with Pd (OAc) 2 afforded the cis-configured bis (carbene) Pd (II) complex (cis-3), which in solution exists as an inseparable mixture of cis–anti and cis–syn-rotamers in a 3.5: 1 ratio. All new ...
