  2. Bromocyclohexane - Wikipedia

    en.wikipedia.org/wiki/Bromocyclohexane

    Due to the moderate dielectric constant of CXB (ε = 7.9 [2]), PMMA acquires charges that can be screened by the addition of salt (e.g. tetrabutyl ammonium bromide), leading to a very good approximation of colloidal hard sphere. [3]

  3. Living cationic polymerization - Wikipedia

    en.wikipedia.org/wiki/Living_cationic_polymerization

    Living cationic polymerization is a living polymerization technique involving cationic propagating species. [1] [2] It enables the synthesis of very well defined polymers (low molar mass distribution) and of polymers with unusual architecture such as star polymers and block copolymers and living cationic polymerization is therefore as such of commercial and academic interest.

  4. Reactivity series - Wikipedia

    en.wikipedia.org/wiki/Reactivity_series

    Standard electrode potentials offer a quantitative measure of the power of a reducing agent, rather than the qualitative considerations of other reactive series. However, they are only valid for standard conditions: in particular, they only apply to reactions in aqueous solution.

  5. trans-Cyclooctene - Wikipedia

    en.wikipedia.org/wiki/Trans-Cyclooctene

    3 I. (Similar procedures can give cis,trans isomers of 1,4-cyclooctadiene and 1,5-cyclooctadiene). [2] In addition, a photochemical method exists for the direct cis–trans isomerisation. Although this equilibrium strongly favours the more stable cis form, the reaction can be driven towards the trans form by trapping with silver ions. [11] [12]

  6. Chemoselectivity - Wikipedia

    en.wikipedia.org/wiki/Chemoselectivity

    Chemoselectivity is the preferential reaction of a chemical reagent with one of two or more different functional groups. [1]In a chemoselective system, a reagent in the presence of an aldehyde and an ester would mostly target the aldehyde, even if it has the option to react with the ester.

  7. Superelectrophilic anion - Wikipedia

    Furthermore, if a variant is more reactive towards a particular reaction partner than another variant, this does not mean that it is universally more reactive. For example, [B 12 Cl 11 ] – binds noble gases more strongly than [B 12 F 11 ] – , but the latter binds CO and N 2 more strongly.

  8. Racemization - Wikipedia

    en.wikipedia.org/wiki/Racemization

    In chemistry, racemization is a conversion, by heat or by chemical reaction, of an optically active compound into a racemic (optically inactive) form. This creates a 1:1 molar ratio of enantiomers and is referred to as a racemic mixture (i.e. contain equal amount of (+) and (−) forms).

  9. Non-linear effects - Wikipedia

    en.wikipedia.org/wiki/Non-linear_effects

    If the correction factor is less than one, the reaction displays an asymmetric depletion, also known as a negative non-linear effect. In this scenario, the heterochiral catalyst is relatively more reactive than the homochiral catalyst complexes. In this case, the (−)-NLE may result in an overall faster although less selective product ...
