Gaseous boroxine: Mechanism of reaction with boron trihalides
Nadler,Porter, Richard F.
, p. 1192 - 1196 (1967)
Low-pressure reactions of gaseous boroxine (H3B3O3) with boron trihalides to produce dihaloborane and boric oxide have been studied by infrared absorption techniques. Kinetic data indicate that the reaction is close to first order in boroxine pressure. The pressure dependence of BF3 in the BF3-H3B3O3 reaction is close to zero order for BF3 pressures above 10 mm but tends toward a higher order at lower pressures. Reactions are accelerated in cells coated with B2O3(s). Reaction rates increase in the order BF3 3 3. Spectra of products of the reaction of 10B-labeled compounds show that the boron atoms in H3B3O3 appear in HBX2 and the boron atom in BX3 appears in B2O3(s). A surface mechanism which accounts for the 10B distribution in the products is proposed.

The unstable dihaloboranes, HBCl2 and HBBr2, have been generated in the gas phase from the virtually quantitative reaction of gaseous BX3 with solid NaBH4 at ca. 250 deg C.HeI photoelectron spectra have been obtained and interpreted with the aid of ab ini

Hydroboration with haloborane/trialkylsilane mixtures
Soundararajan, Raman,Matteson, Donald S.
, p. 4157 - 4166 (2008/10/09)
Trialkylsilanes or dialkylsilanes react rapidly with boron trichloride in the absence of ethereal solvents or other nucleophiles to form unsolvated dichloroborane. If no substrate is present, dichloroborane disproportionates to trichloroborane and two geo
Interaction of metal carbonyl hydrides with Lewis acids
Richmond, Thomas G.,Basoio, Fred,Shriver, Ouward F.

Recent studies on Lewis acid promoted CO migratory insertion to produce metal acyls prompted a comprehensive study of the interaction of metal carbonyl hydrides with molecular Lewis acids. Stable rnetal formyl formation was not achieved in this study, but insight was obtained into reactions that may compete with migratory insertion in metal carbonyl hydrides. The reactivity of metal carbonyl hydrides with strong Lewis acids is dominated by the basic character of the hydride ligand. Variable-temperature multinuclear NMR characterization of the low-temperature complex Mn(CO)5-H-BCl3 is presented. The susceptibility to electrophilic metal hydrogen bond cleavage increases with decreasing acidity of the hydride, Steric factors are also important as evidenced by the observation that H3Re3(CO)12 is much more resistant to eiectrophilic attack than is HRe(CO)5. Also discussed are reactions of Lewis acids with HCo(CO)4, [PPN][HFe(CO)4], [Ir(CO)2(PPh3)2H2][BPh4], HMn(CO)4PPh3, CpMo(CO)3H; and CpMo(CO)2(PPh3)H.
