Oxidative and cluster Aufbau reactions of nido-6-metalladeaboranes induced by Lewis bases such as SMe2: high-yield formation of [1-(η6-C6Me6)-isocloso-1-RuB9H9] and the molecular structure of the Rh-commo-(isonido-eleven-vertex)-(closo-ten-vertex)conjuncto species [(η5-C5Me5)RhB9(SMe2)H10RhB9H7(SMe2)2]

Abstract

The reaction of SMe₂ with [6-(η⁶-C₆Me₆)-nido-6-RuB₉H₁₃] gives an 80% yield of [1-(η⁶-C₆Me₆)-isocloso-1-RuB₉H₉], whereas reaction with the analogous [6-(η⁵-C₅Me₅)-nido-6-RhB₉H₁₃] gives a variety of products, of which one (20%) is the novel conjuncto species [(η⁵-C₅Me₅)RhB₉(SMe₂)H₁₀RhB₉H₇(SMe₂)₂] that has a structure based on a unique isonido-type eleven-vertex {7′,9′-Rh₂B₉} and a closo ten-vertex {2-RhB₉} cluster joined at a common rhodium atom.
