Synthesis and Reactions of Novel Bridged Dicarbollide Complexes Having Electron Deficient Carbon Atoms

摘要

Reaction of the bis-pi-dicarbollide ligand complexes of Co(+3) and Fe(+3) with CS2 in the presence of AlCl3 and HCl produced the firts examples of zwitterionic species having an -S-CH(+)-S- bridge between boron atoms of the two dicarbollide ion ligands of the complex. Similarly, a suspected -OC(CH3)(+)O- bridged species results from the reaction of acetic acid/acetic anhydride with an HClO4 catalyst. Further transformations of these species are described. (Author)
