Upon reaction with SMe2, [2,4-Cl-2-nido-B10H12] gives [6,9-(SMe2)(2)-1,7-Cl
-2-arachno-B10H10] and [1,2,4-Cl-3-nido-B10H11] gives [6,9-(SMe2)(2)-1,3,7-
Cl-3-arachno-B10H9](1), demonstrating a previously unsuspected fundamental
rearrangement for the 10-boron arachnolnido cluster type. (C) 2001 Elsevier
