摘要：

The reactivity of two isoelectronic and isostructural metallaboranes, nido-[(Cp*Rh)(2)B6H10], 1 and nido[( Cp*Ru)(2)B6H12], 2 with alkynes demonstrates that a change in metal from group 9 to group 8 creates difference in the reactivity pattern. Compound 1 catalyzes the cyclotrimerization of a variety of internal and terminal alkynes to yield 1,3,5-and 1,2,4-substituted benzene. In contrast, compound 2 shows no reactivity toward alkynes. A set of alkynes have been verified with nido-1 that yielded several benzene derivatives in satisfactory yields. (C) 2013 Elsevier B. V. All rights reserved.
