NH3BF3adduktio

NH3BF3adduktio, also known as the adduct of ammonia and boron trifluoride, is a chemical compound formed by the reaction between ammonia (NH3) and boron trifluoride (BF3). In this reaction, the Lewis base ammonia donates a lone pair of electrons to the Lewis acid boron trifluoride, forming a coordinate covalent bond. The resulting adduct has the chemical formula NH3BF3.

This adduct is typically a white solid and is relatively stable compared to the individual reactants. It is important to note that boron trifluoride is a gas at room temperature and is highly reactive, while ammonia is also a gas. The formation of the adduct neutralizes some of the reactivity of both components.

NH3BF3 is often encountered in organic synthesis. It can serve as a source of a Lewis acid catalyst. For instance, it can be used in reactions such as Friedel-Crafts alkylations and acylations, or in polymerization processes. The adduct can also be employed as a fumigant or as a reagent in certain analytical procedures. The stability of the adduct allows for easier handling and storage of boron trifluoride in a less hazardous form. When needed, the adduct can be decomposed, usually by heating, to regenerate the reactive boron trifluoride.
