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.

Structures of Tetrahalodiboranes. Tetrahalodiboranes are a class of diboron compounds with the formula B 2 X 4 (X = F, Cl, Br, I). These compounds were first discovered in the 1920s, [1] but, after some interest in the middle of the 20th century, were largely ignored in research.
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.

Diborane(4) is a transient inorganic compound with the chemical formula B 2 H 4.Stable derivatives are known. Diborane(4) has been produced by abstraction of two hydrogen atoms from diborane(6) using atomic fluorine and detected by photoionization mass spectrometry. [1]
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]
