Abstract
The first example of B,C'-bridging in the commo bis(dicarbollide) seri es are presented. The sandwich metallacarborane synthesized is neutral due to the formation of a sulfonium group bridging one carbon from on e half and one boron from the second half to yield ',8-mu-SEt-3,3'-Co( 1-Ph-2-SEt-1,2-C2B9H9)(9'Ph-1', 9'-C2B9H8)] A nucleophilic substitutio n is involved to account for its formation. A rearrangement from 3,1,2 -CoC2B9 to 3,1,9-CoC2B9 has taken place. The molecular structure is pr oven by an X-ray analysis.
