Oxidative addition of boron–boron, boron–chlorine and boron–bromine bonds to platinum(0)
Journal of Organometallic Chemistry, 1998Abstract The synthesis and spectroscopic characterisation of the new diborane(4) compounds B2(1,2-O2C6Cl4)2 and B2(1,2-O2C6Br4)2 are reported together with the diborane(4) bis-amine adduct [B2(calix)(NHMe2)2] (calix=Butcalix[4]arene). B–B bond oxidative addition reactions between the platinum(0) compound [Pt(PPh3)2(η-C2H4)] and the diborane(4 ...

Vapor transport of boron, boron phosphide and boron arsenide
Journal of Crystal Growth, 1967Abstract Small crystals of boron, boron phosphide and boron arsenide have been produced by chemical vapor transport using halogens as transporting reagent. In all cases the material transported from a higher to a lower temperature. The boron phosphide and boron arsenide produced were cubic while the boron was beta-rhom-bohedral.

Science, 1965
A hitherto undescribed form of boron can be prepared by subjecting ordinary forms of boron to pressures exceeding about 100 kilobars and temperatures between about 1500° to 2000°C. The new form has a density of about 2.52 g/cm 3 and yields a characteristic DeBye-Scherrer pattern. No large crystals have been prepared.

Boron Analysis and Boron Imaging in BNCT
2012Boron neutron capture therapy (BNCT) strongly depends on the selective uptake of 10B in tumor cells and on the 10B distribution inside single cells. The chemical properties of boron and the need to discriminate different isotopes make the investigation of the concentration and distribution of 10B a challenging task.
