regioselectivity การใช้

ประโยคมือถือ
  • The regioselectivity of water elimination is highly influenced by ring size.
  • Both the regioselectivity and the resonance structures and the inductive effect.
  • FMO theory is used to predict the regioselectivity of the reagents.
  • This method forms diastereomers, possibly affecting the regioselectivity of the reaction.
  • It has been shown that the Demjanov reaction is susceptible to regioselectivity.
  • Regioselectivity in ring-closure reactions is subject to Baldwin's rules.
  • In terms of regioselectivity, the catalyzed hydroboration differs from the uncatalyzed parallel.
  • The explanation for the reverse regioselectivity which produced the iso-tryptophan is unknown.
  • The difference in regioselectivity is more pronounced in the hydroboration of vinylarenes with HBcat.
  • This regioselectivity does not appear to depend on conjugation or the degree of substitution.
  • However, these reactions can have low regioselectivity and are prone to over substitution.
  • The intramolecular nature of the reaction can also be useful in that regioselectivity is often constrained.
  • The placement preference of groups during the reaction and in the final product is termed regioselectivity.
  • Therefore, regioselectivity is governed by the atoms that bear the largest orbital HOMO and LUMO coefficients.
  • With unsymmetrical alkenes or alkynes, regioselectivity can be problematic, but less so with intramolecular reactions.
  • Interestingly, this reaction produced the product which had the reverse regioselectivity of normal Larock indole synthesis.
  • The regioselectivity of the reaction is due to the significant positive character developed at the tertiary carbon.
  • Selectivity in terms of regioselectivity, diastereoselectivity and enantioselectivity is therefore an important criterion for many organic reactions.
  • The hydroformylation is a reaction with high atom economy, especially if the reaction proceeds with high regioselectivity.
  • In most cases, the regioselectivity was poor although the ee values can be close to 90 %.
