A species' ability to serve as a leaving group depends on its ability to stabilize the additional electron density that results from bond heterolysis.
23 Ιαν 2023 · Halides are an example of a good leaving group whos leaving-group ability increases as you go down the column. The two reactions below is the same reaction done with two different leaving groups. One is significantly faster than the other.
11 Οκτ 2012 · The “element effect” in nucleophilic aromatic substitution reactions (S N Ar) is characterized by the leaving group order, F > NO 2 > Cl ≈ Br > I, in activated aryl halides. Multiple causes for this result have been proposed.
The leaving group is the part of the substrate that is missing at the end of the reaction. The equation for a typical nucleophilic substitution reaction is Nu⁻ + R-L → Nu-R + L⁻
7 Αυγ 2012 · Adding Acid Increases Leaving Group Ability. Sure, it’s one thing to recognize halogens (Cl, Br, and I) as having high leaving group ability, as well as tosylate (TsO- ) and mesylate (MsO-) but what if you have a functional group like HO- ? How do you get that pesky hydroxide to leave? Read on! Table of Contents
15 Μαρ 2018 · Employing CN − as a nucleophile and Cl − as a leaving group, they investigated substitution patterns on the alkyl halide, including α- and β-methylation, adjacent unsaturated functional groups (allyl, benzyl, propargyl, α to carbonyl), ring size, and α-halogenation and cyanation.
