  • One example of the Strecker synthesis is a multikilogram scale synthesis of an L-valine derivative starting from Methyl isopropyl ketone: The asymmetric Strecker reaction was pioneered by Kaoru Harada in 1963. (wikipedia.org)
  • doi:10.1021/jo7012862 The initial reaction product of 3-methyl-2butanone with sodium cyanide and ammonia is resolved by application of L-tartaric acid. (wikipedia.org)
  • The Tishchenko reaction of paraformaldehyde in the presence of aluminum methylate or magnesium methylate forms methyl formate. (wikipedia.org)
  • The haloform reaction is a chemical reaction where a haloform (CHX3, where X is a halogen) is produced by the exhaustive halogenation of a methyl ketone (a molecule containing the R-CO-CH3 group) in the presence of a base. (wikipedia.org)
  • This reaction forms the basis of the iodoform test which was commonly used in history as a chemical test to determine the presence of a methyl ketone, or a secondary alcohol oxidizable to a methyl ketone. (wikipedia.org)
  • In organic chemistry, this reaction may be used to convert a terminal methyl ketone into the analogous carboxylic acid. (wikipedia.org)
  • As implied by its name, it is a trimeric species formed from the reaction of acetaldehyde and ammonia: 3 CH3CHO + 3 NH3 → (CH3CHNH)3 + 3 H2O Studies using NMR spectroscopy indicate that the three methyl groups are equatorial, thus the molecule has C3v point group symmetry. (wikipedia.org)
  • produce
  • The reaction can be used to transform acetyl groups into carboxyl groups or to produce chloroform (CHCl3), bromoform (CHBr3), or iodoform (CHI3). (wikipedia.org)
  • known
  • The nuclear magnetic resonance spectrum shows that there are three environments for protons, in the ratio of 3:2:1 corresponding to CH3 SH and CH. 1,1-Ethanedithiol has several reactions known that are important in white wine flavours. (wikipedia.org)
  • This reaction is also known as the Morita-Baylis-Hillman reaction or MBH reaction. (wikipedia.org)
  • structures
  • Kekulé suggested in reply that benzene had two complementary structures and that these forms rapidly interconverted, which would also explain the lack of addition reactions (as the valency of each carbon atom is not that expected of a double bond). (wikipedia.org)

  • 3) Reaction products usually contain multiple functionalities in a proximity so that a variety of further transformations are possible. (wikipedia.org)
