Abstract

Reaction between Tl₂[7,8-Ph₂-7,8-nido-C₂B₉H ₉] and NiCl₂(PR₃)₂ in CH₂Cl₂ affords three new carbanickelaboranes; 1, R₃=Me₂Ph; 2, R=Et; 3, (PR₃)₂=dppe. The molecular structures of all these compounds were established as 1,2-Ph₂-4,4-(PR₃)₂-4,1,2-closo-NiC ₂B₉H₉ by spectroscopic and crystallographic techniques. It is presumed that the first (transient) products of the reactions are the compounds 1,2-Ph₂-3,3-(PR₃)₂-3,1,2-closo-NiC ₂B₉H₉ which rearrange to the observed species by a '1,2 to 1,2' C_cage atom isomerisation to relieve intramolecular overcrowding. © 1999 Elsevier Science S.A.
