WebBoron trifluoride is a versatile Lewis acid that forms adducts with such Lewis bases as fluoride and ethers : CsF + BF 3 → CsBF 4. O (C 2 H 5) 2 + BF 3 → BF 3 ·O (C 2 H 5) 2. Tetrafluoroborate salts are commonly employed as non-coordinating anions. http://wrg.rice.edu/Whitmire_Research_Group/q059.html

WebHaloform Reaction Mechanism. Haloform reaction mechanism starts with the disproportionation of the halogen with the presence of the hydroxide ion. This gives the halide or the hypohalite. The hydroxide abstracts the proton, producing enolate. The hypohalite also reacts with any present methyl ketones, eventually forming a haloform.
