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.
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.

This is a list of common chemical compounds with chemical formulae and CAS numbers, indexed by formula. This complements alternative listing at list of inorganic compounds . There is no complete list of chemical compounds since by nature the list would be infinite.
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]
