• hydrogen
  • An example of alpha halogenation is the mono-bromination of acetone, carried out under either acidic or basic conditions, to give bromoacetone: Acidic (in acetic acid): Basic (in aqueous NaOH): In acidic solution, usually only one alpha hydrogen is replaced by a halogen, because each successive halogenation is slower than the first. (wikipedia.org)
  • electron
  • Halogen can leave with the electron pair. (slideplayer.com)
  • However, in basic solution successive halogenations are more rapid due to inductive electron withdrawal by the halogen, making the remaining hydrogens more acidic. (wikipedia.org)
  • Halogenation of phenols is faster in polar solvents due to the dissociation of phenol, with phenoxide ions being more susceptible to electrophilic attack as they are more electron-rich. (wikipedia.org)
  • undergo
  • HCl Because halogenated ethanes can undergo further free radical halogenation, this process results in a mixture of several halogenated products. (wikipedia.org)
  • carbon atom
  • From the structural perspective, haloalkanes can be classified according to the connectivity of the carbon atom to which the halogen is attached. (wikipedia.org)
  • In describing these, it is useful to designate the halogen-bearing carbon as alpha and the carbon atom(s) adjacent to it as beta , as noted in the first four equations shown below. (msu.edu)
  • carbanion
  • In the Favorskii rearrangement a base abstacts first an acidic α-proton and the resulting carbanion then displaces the halogen. (wikipedia.org)
  • The negative charge placed on this position (formally a carbanion) is transferred to the halogen residing on the other α-position in a nucleophilic displacement temporarily forming a three-membered cyclic sulfone. (wikipedia.org)
  • type
  • Haloalkanes can also be classified according to the type of halogen on group 7 responding to a specific halogenoalkane. (wikipedia.org)
  • bond
  • Abstract A halogen bond catalyzed bromo‐carbocyclization of N‐cinnamyl sulfonamides and O‐cinnamyl phenyl ethers has been developed. (chemistryviews.org)
  • alkylating agents
  • Many are alkylating agents, with primary haloalkanes and those containing heavier halogens being the most active (fluoroalkanes do not act as alkylating agents under normal conditions). (wikipedia.org)
