An important synthetic application using such dialkylboranes, such as diethylborane, is the transmetallation of the organoboron compounds to form organozinc compounds. [9] [10] Some diaryl and dialkylboranes are well known. Dimesitylborane is a dimer (C 6 H 2 Me 3) 4 B 2 H 2). It reacts only slowly with simple terminal alkenes.
Zinc borate refers to a family of inorganic compounds consisting of borate of zinc.They are white solids with the formulas 4ZnO·B 2 O 3 ·H 2 O, ZnO·B 2 O 3 ·1.12H 2 O, ZnO·B 2 O 3 ·∼2H 2 O, 6ZnO·5B 2 O 3 ·3H 2 O, 2ZnO·3B 2 O 3 ·7H 2 O, 2ZnO·3B 2 O 3 ·3H 2 O, 3ZnO·5B 2 O 3 ·14H 2 O, and ZnO·5B 2 O 3 ·4.5H 2 O.
The tetrapropylboranuide anion is a reagent for the propylation of organometallic compounds, including organotin, organomercury, and organolead compounds of interest to environmental and public health research. [4]
Many sodium borates have important industrial and household applications; the best known being borax, (Na +) 2 [B 4 O 5 (OH) 4] 2− ·8H 2 O = Na 2 B 4 H 20 O 17. The ternary phase diagram of the Na 2 O – B 2 O 3 – H 2 O phase diagram in the 0–100 °C temperature range contains 13 unique hydrated crystalline sodium borates, including ...
Borate ions occur, alone or with other anions, in many borate and borosilicate minerals such as borax, boracite, ulexite (boronatrocalcite) and colemanite. Borates also occur in seawater, where they make an important contribution to the absorption of low frequency sound in seawater. [1] Borates also occur in plants, including almost all fruits. [2]

Trimethyl borate is the organoboron compound with the formula B(OCH 3) 3 and a metal alkoxide. It is a colourless liquid that burns with a green flame. [1] It is an intermediate in the preparation of sodium borohydride and is a popular reagent in organic chemistry. It is a weak Lewis acid (AN = 23, Gutmann-Beckett method). [2]
A metaborate is a borate anion consisting of boron and oxygen, with empirical formula BO − 2.Metaborate also refers to any salt or ester of such anion (e.g. salts such as sodium metaborate NaBO 2 or calcium metaborate Ca(BO 2) 2, and esters such as methyl metaborate CH 3 BO 2).
