Boron monoxide (BO) is a binary compound of boron and oxygen. It has a molar mass of 26.81 g/mol. It has a molar mass of 26.81 g/mol. The material was first reported in 1940, [ 1 ] with a modified synthetic procedure published in 1955, [ 2 ] however, the material's structure had remained unknown for nearly a century.
In the diamond-like structure, called cubic boron nitride (tradename Borazon), boron atoms exist in the tetrahedral structure of carbon atoms in diamond, but one in every four B-N bonds can be viewed as a coordinate covalent bond, wherein two electrons are donated by the nitrogen atom which acts as the Lewis base to a bond to the Lewis acidic ...
Organoboron chemistry is mainly of commercial value in the pharmaceutical industry. Triethylborane was used to ignite the JP-7 fuel of the Pratt & Whitney J58 variable cycle engines powering the Lockheed SR-71 Blackbird. Organoboron compounds have long been discussed for use as boron delivery agents in neutron capture therapy of cancer. [49]
Boron monofluoride monoxide or oxoboryl fluoride [2] or fluoroxoborane is an unstable inorganic molecular substance with formula FBO. It is also called boron fluoride oxide, fluoro(oxo)borane or fluoro-oxoborane. The molecule is stable at high temperatures, but below 1000 °C condenses to a trimer (BOF) 3 called trifluoroboroxin.
Boron oxide may refer to one of several oxides of boron: Boron trioxide (B 2 O 3, diboron trioxide), the most common form; Boron monoxide (BO) Boron suboxide (B 6 O)
This procedure is used for analysis of trace amounts of borate and for analysis of boron in steel. [2] Like all boron compounds, alkyl borates burn with a characteristic green flame. This property is used to determine the presence of boron in qualitative analysis. [3] Trimethyl borate is a popular borate ester used in organic synthesis.
It is prepared commercially by reduction of MnO 2 with hydrogen, carbon monoxide or methane, e.g.: [2] MnO 2 + H 2 → MnO + H 2 O MnO 2 + CO → MnO + CO 2. Upon heating to 450 °C, manganese(II) nitrate gives a mixture of oxides, MnO 2−x, which can be reduced to the monoxide with hydrogen at ≥750 °C. [6]
Boron monofluoride or fluoroborylene is a chemical compound with the formula BF, one atom of boron and one of fluorine. It is an unstable gas, but it is a stable ligand on transition metals, in the same way as carbon monoxide. It is a subhalide, containing fewer than the normal number of fluorine atoms, compared with boron trifluoride.
