资源简介:
A new CCC-NHC pincer ligand precursor architecture based on 1,3-bis­(N-alkylbenzimidazole)­benzene has been synthesized and metalated using Ag2O, forming a homobimetallic Ag complex with a metal to ligand ratio of 1:1. The Ag complex was treated with either [Rh­(COD)­Cl]2 or Rh­(COD)2OTf and NBu4I to yield a homobimetallic Rh complex by transmetalation. The Rh complexes were characterized, and an X-ray structure is reported. Their catalytic activity in the hydrosilylation of phenylacetylene is reported.
