The reaction of boron trichloride with alcohols was reported in 1931, and was used to prepare dimethoxyboron chloride, B(OCH 3) 2 Cl. [3] Egon Wiberg and Wilhelm Ruschmann used it to prepare tetrahydroxydiboron by first introducing the boron–boron bond by reduction with sodium and then hydrolysing the resulting tetramethoxydiboron, B 2 (OCH 3) 4, to produce what they termed sub-boric acid.

Some representative reactions showing 1,2-addition of diboron tetrachloride to hydrocarbons. Some of these reactions can also be carried out under more forcing conditions with diboron tetrafluoride. Tetrahalodiboranes can add to unsaturated hydrocarbons. Schlesinger et al. published 1,2-additions of B 2 Cl 4 to ethylene and acetylene. [16]

Barium borate is an inorganic compound, a borate of barium with a chemical formula BaB 2 O 4 or Ba(BO 2) 2. It is available as a hydrate or dehydrated form, as white powder or colorless crystals. The crystals exist in the high-temperature α phase and low-temperature β phase, abbreviated as BBO ; both phases are birefringent , and BBO is a ...

Boron trioxide or diboron trioxide is the oxide of boron with the formula B 2 O 3. It is a colorless transparent solid, almost always glassy (amorphous), which can be crystallized only with great difficulty.
Tetraborane (systematically named arachno-tetraborane(10)) was the first boron hydride compound to be discovered. [2] It was classified by Alfred Stock and Carl Massenez in 1912 and was first isolated by Stock. [3]
This is the fourth member of the polyoxidanes. The first three are water [(mon)oxidane], hydrogen peroxide (dioxidane), and trioxidane.Tetraoxidane is more unstable than the previous compounds.
