  Indenyl Ligands as Supports for Reactive, Low-Valent Cobalt(I) Fragments

  摘要：

  Alkali-metal reduction of (eta(5)-C9H5-1,3(SiMe3)(2))(2)Co (1) in the presence of vinyltrimethylsilane affords the unusual indenyl cobalt(I) dimer 3, where interligand eta(4)-benzo coordination is achieved. Though an aggregate, 3 serves as a ready source of a 14-electron indenyl cobalt(I) equivalent, on the basis of competition experiments between 3 and (eta(5)-C9H5-1,3-(SiMe3)(2))Co(COD) (2) with carbon monoxide. The enhanced reactivity of 3 brought about by benzo coordination, relative to a typical donor-ligated source of Co(I), suggests the compound may serve as a promising platform for small-molecule activation and functionalization.

  for the one electron reduction from Co(II) to Co(I). Reactivity studies of 2 are further consistent with a Co(I) equivalent, based on both one electron chemical oxidation to reform 1 and reaction with a variety of σ and π donors. Upon addition of pyridines or vinyltrimethylsilane to 2, known dimer [(C9H5-1,3-(SiMe3)2)2Co2] (3) is formed, likely through 16 electron (η5-C9H5-1,3-(SiMe3)2)Co(L) intermediates
