Borane, also known as borine, is an unstable and highly reactive molecule with the chemical formula B H. 3. The preparation of borane carbonyl, BH 3 (CO), played an important role in exploring the chemistry of boranes, as it indicated the likely existence of the borane molecule. [2] However, the molecular species BH 3 is a very strong Lewis acid.
Infobox references. Ammonia borane (also systematically named ammoniotrihydroborate[citation needed]), also called borazane, is the chemical compound with the formula H3NBH3. The colourless or white solid is the simplest molecular boron - nitrogen - hydride compound.
Contents. Lewis acids and bases. A Lewis acid (named for the American physical chemist Gilbert N. Lewis) is a chemical species that contains an empty orbital which is capable of accepting an electron pair from a Lewis base to form a Lewis adduct. A Lewis base, then, is any species that has a filled orbital containing an electron pair which is ...
t. e. The Brønsted–Lowry theory (also called proton theory of acids and bases[1]) is an acid–base reaction theory which was first developed by Johannes Nicolaus Brønsted and Thomas Martin Lowry independently in 1923. [2][3] The basic concept of this theory is that when an acid and a base react with each other, the acid forms its conjugate ...
Boranes. Triethylboron is a trialkylborane. A borane is a compound with the formula BRxHy although examples include multi-boron derivatives. A large family of boron hydride clusters is also known. In addition to some applications in organic chemistry, the boranes have attracted much attention as they exhibit structures and bonding that differs ...
A good example is the formation of adducts between the Lewis acid borane and the oxygen atom in the Lewis bases, tetrahydrofuran (THF): BH 3 ·O(CH 2) 4 or diethyl ether: BH 3 ·O(CH 3 CH 2) 2. Many Lewis acids and Lewis bases reacting in the gas phase or in non-aqueous solvents to form adducts have been examined in the ECW model. [3]
Borane carbonyl is the inorganic compound with the formula H 3 B C O. This colorless gas is the adduct of borane and carbon monoxide. It is usually prepared by combining borane-ether complexes and CO. The compound is mainly of theoretical and pedagogical interest. [2]
Hydroboration. In organic chemistry, hydroboration refers to the addition of a hydrogen - boron bond to certain double and triple bonds involving carbon (C=C, C=N, C=O, and C≡C). This chemical reaction is useful in the organic synthesis of organic compounds. Hydroboration produces organoborane compounds that react with a variety of reagents ...
