Abstract

We propose a mechanism for the cage-opening reaction of a four atoms shared closo/closo $B_{20}H_{16}$ (1) with MeCN to a face shared closo/nido macropolyhedron $B_{20}H_{16}(MeCN)_2$ (4) through a diamond-square-diamond rearrangement. Even though only one isomer of the product has been reported experimentally, our computational studies at the B3LYP/6-31G* level predict the possibility of the formation of the other isomers. Depending upon the position of the attack of the MeCN ligand on the polyhedral skeleton, different products are formed. The energetics of the reactions of $B_{20}H_{16}$ with $Me_2S$ and $H_2O$ are comparable.
