Molecular wheels of eight-and nine-atom boron clusters have been observed by photoelectron spectroscopy and their structures confirmed by DFT calculations. 1 The first cationic terminal borylene, containing a FeLB double bond, [Cp*Fe(CO) 2 -(Bmesityl)][BAr f4 ] has been synthesised. DFT calculations support a bonding model in which boron engages in p-bonding to both [Cp*Fe(CO) 2 ] 1 and mesityl moieties. 2 The first thirteen vertex carborane has been prepared by successive reduction of 1,2-m-{C 6 H 4 (CH 2 ) 2 }-1,2-closo-C 2 B 10 H 10 with Na to afford the [7,8-m-{C 6 H 4 (CH 2 ) 2 }-7,8-nido-C 2 B 10 H 10 ] 22 ion followed by addition of PhBCl 2 to give the unprecedented 13-vertex carborane 1,2-m-{C 6 H 4 (CH 2 ) 2 }-3-Ph-1,2-C 2 B 11 H 10 which has a henicosahedral structure. 3

“…Alternatively, polyhedral boranes can react with Lewis bases to form borane adducts with displacement of molecular hydrogen, without cleavage of the cluster framework [4,5]. In contrast to polyhedral boranes, relatively little work has been carried out on the reaction of Lewis bases with metallaboranes [6][7][8][9][10]. Macías and co-workers report that the reaction of the iridaborane arachno-1-[Ir(g-C 5 Me 5 )(H)B 4 H 9 ] with a range of phosphines and amines (excess) leads to {BH 3 } or {2H} abstraction and the formation of the metallaboranes arachno-1-Ir(g-C 5 Me 5 )(H)-(L)B 3 H 7 and nido-1-[Ir(g-C 5 Me 5 )(H)B 4 H 7 ], respectively (L = Lewis base).…”
