The reaction of [C2B10H11CH2NH3]Cl (3) with [NH4]6[Mo7O24][H2O]4 in water instantly afforded a white precipitate: crystallization from acetone–hexane thence gave the hybrid dicarborane octamolybdate salt, [C2B10H11CH2NH3]2[C2B10H11CH2NH=CMe2]2[Mo8O

Sterically highly hindered phosphiniminato complexes MCl3(NCP) were prepared from MCl4 and Li[NPC] in toluene [M = Zr or Hf; NPC = 4-ButC6H4C(SiMe3)P(Ph)2 NC6H2Me3-2,4,6]. Reaction with methyl lithium readily affords the corresponding zirconium and h

Compared to the chemistry associated with the basic syntheses and structures of the metallaboranes, their reaction chemistry is relatively uninvestigated. To illustrate the potential variety of such reaction chemistry, a linked overview of some previ

Reaction of terBuNC with anti-B18H22 in CH2ClCH2Cl gives [7-{(terBuNHCH){terBuNHC(CN)}CH2}-anti-B18H20] in which a reductive oligomerisation of the terBuNC residues has given the complex polynitrogen base {(terBuNHCH){terBuNHC(CN)}CH2:}, formally as

Reaction of [{RuCl2(η6-MeC6H4isoPr)}2] with syn-[B18H22] and non-nucleophilic base results in [8-(η6-MeC6H4isoPr)-8-RuB17H21], of 18-vertex anti 10-vertex-nido-10-vertex-nido configuration, as the predominant product. The syn → anti configuration

Reaction between PhC?CH and [4,4-(PMe2Ph)2-arachno-4-PtB8H12] (1) gives carbons-apart [7,7-(PMe2Ph)2-isonido-7,6,8-PtC2B6H7-6-Ph] (2), in a ‘converse’ synthesis of a metallacarbaborane, viz. in a synthesis by addition of carbon centres into a pre

Structurally characterised 17-vertex [(PMe2Ph)2PtB16H17Me] 3 is obtained, albeit in low yield, by platination of 16-vertex B16H201 using [PtMe2(PMe2Ph)2] under mild conditions. Platination has occurred on the {B10} subcluster of 1, interesting in tha

The enantioselective addition of diorgano-H-phosphonates to aldehydes, the phospho-aldol reaction, is catalysed by both (R,R)-salcyen and (R,R)-salcyan complexes of aluminium at room temperature under aerobic conditions. However, whilst the former li

Crystal structure of two brom containing aza-tetracyclic fused N-heterocycles including isoxazolidine ring compounds have been determined in single-crystal X-ray diffraction studies. The compound, C14H19BrN2O3, (1), and C12H15BrN2O3, (2), were obtain

Fused double-cluster [(η5-C5Me5)IrB18H18(PH2Ph)] (8), from syn-[(η5-C5Me5)IrB18H20] (1) and PH2Ph, retains the three-atoms-in-common cluster fusion intimacy of 1, in contrast to [(η5-C5Me5)HIrB18H19(PHPh2)] (6), from PHPh2 with 1, which exhibits a
