Catalysis with clusters : Transition metal characteristics control metallaborane reactivity as demonstrated by the reaction of a pair of isoelectronic and nearly isostructural metallaboranes with substituted alkynes. Novel catalytic chemistry of nido ‐[1,2‐(Cp*Rh) 2 B 3 H 7 ] and nido ‐[2,3‐(Cp*Rh) 2 B 3 H 7 ] (shown) with alkynes (see scheme) is observed with activities and selectivities that depend on catalyst structure and the alkyne substituents.
