  • Haloform reaction - Wikipedia
    In chemistry, the haloform reaction (also referred to as the Lieben haloform reaction) is a chemical reaction in which a haloform (CHX3, where X is a halogen) is produced by the exhaustive halogenation of an acetyl group (R−C (=O)CH3, where R can be either a hydrogen atom, an alkyl or an aryl group), in the presence of a base [1][2][3] The
  • Haloform Reaction: Definition, Examples, and Mechanism
    Definition: What is Haloform Reaction? The Haloform reaction is a chemical reaction where haloforms (CH 3 X) are produced by the complete halogenation of acetone (CH 3 COCH 3), acetophenone (PhCOCH 3), or acetaldehyde (HCOCH 3) in the presence of a base
  • Haloform Reaction - Chemistry LibreTexts
    The haloform reaction is the reaction of a methyl ketone with chlorine, bromine, or iodine in the presence of hydroxide ions to give a carboxylate ion and a haloform
  • 200 Years of The Haloform Reaction: Methods and Applications
    Discovered in 1822, the haloform reaction is one of the oldest synthetic organic reactions The haloform reaction enables the synthesis of carboxylic acids, esters or amides from methyl ketones
  • Haloform Reaction - Chemistry Steps
    In the last step, the deprotonation of the carboxylic acid results in a haloform which is the basis of the reaction name The haloform reaction is mostly known for the reaction of methyl ketones with iodine
  • Haloform Reaction - Organic Chemistry Portal
    The reaction has some synthetic utility in the oxidative demethylation of methyl ketones if the other substituent on the carbonyl groups bears no enolizable α-protons The reaction readily proceeds to completion because of the acidifying effect of the halogen substituents Recent Literature
  • Haloform Reaction - an overview | ScienceDirect Topics
    The haloform reaction is characteristic for compounds bearing a methyl group adjacent to a carbonylic group, these being the so-called methylketones The reaction is carried out using chlorine in basic media to give a carboxylic acid
  • Haloform Reaction of Methyl Ketones – Master Organic Chemistry
    The iodoform test is an example of the haloform reaction, which uses an excess of base (usually hydroxide) and an excess of halogen to produce a carboxylic acid and a haloform
  • Ch18: Haloform reaction - Faculty of Science
    The products are the carboxylate and trihalomethane, otherwise known as haloform The reaction proceeds via successively faster halogenations at the α-position until the 3 H have been replaced
