• ethylene

  • ether
  • Extractives are generally classified as water-soluble, toluene-ethanol-soluble, or ether-soluble, according to the extractive solvent. (sisef.it)
  • It has a tertiary amine group, an amide, an alkene and an ether group. (wikipedia.org)
  • Treatment of the phenylaziridinylhydrazone with 0.3 equivalents of LDA in ether resulted in the alkene shown below with a cis:trans ratio of 99.4:0.6. (wikipedia.org)
  • nucleophile
  • ruling out extreme cases, the water nucleophile will always preferentially attack the more substituted carbon, depositing the resultant hydroxy group there. (wikipedia.org)
  • In the first step, the alkene acts as a nucleophile and attacks the proton, following Markovnikov's rule. (wikipedia.org)
  • aqueous solution
  • Rhodium(II) acetate dimer, compared to copper(II) acetate, is more reactive and useful in differentiating ribonucleosides and deoxynucleosides because it is soluble in aqueous solution like water whereas copper(II) acetate only dissolves in non-aqueous solution. (wikipedia.org)
  • carbons
  • Smaller carboxylic acids (1 to 5 carbons) are soluble in water, whereas higher carboxylic acids are less soluble due to the increasing hydrophobic nature of the alkyl chain. (wikipedia.org)
  • Linear alkenes of approximately five to sixteen carbons are liquids, and higher alkenes are waxy solids. (wikipedia.org)
  • Stereoselective
  • To combat this problem, Yamamoto and coworkers developed an efficient stereoselective and regioselective route to alkenes using a combination of ketone phenylaziridinylhydrazones as arenesulfonylhydrazone equivalents with a catalytic amount of lithium amides. (wikipedia.org)
  • solvent
  • Ab initio calculation was conducted to reveal the origin of the solvent effect of water in the cyclization of allyl iodoacetate. (nii.ac.jp)
  • attacks
  • The alkene attacks NBS to form a bromonium ion (Step 1, arrows A and B) which is attacked at the more substituted carbon by water (Step 2, arrows C and D). The resulting positively charged oxygen is then deprotonated to give the neutral bromohydrin (Step 3, arrows E and F). (masterorganicchemistry.com)
  • With 1-methyl-4-t-butylcyclohexene, oxymercuration yields only one product - still anti addition across the double bond - where water only attacks the more substituted carbon. (wikipedia.org)
  • orbital
  • The reason for anti addition across the double bond is to maximize orbital overlap of the lone pair of water and the empty orbital of the mercurinium ion on the opposite side of the acetoxymercury group. (wikipedia.org)
  • carboxylic
  • Trichloroalkanes of structure CCl 3 CH 2 (CH 2 ) n H (n=5, 7, 9, 11, 13) are hydrolyzed smoothly to the corresponding carboxylic acids when heated with water at 300-330° for one hour. (springer.com)
  • Carboxylic acids tend to have higher boiling points than water, not only because of their increased surface area, but also because of their tendency to form stabilised dimers. (wikipedia.org)
  • transition
  • Regioselectivity is observed to favor water attacking the more substituted carbon, but water does not add syn across the double bond which implies that the transition state favors water attacking from the opposite side of the acetomercury group. (wikipedia.org)
  • metals
  • Cognition Land and Water Ltd, a UK based remediation specialist, has hired a portable XRF metals analyser to improve the speed of remediation work at a project in London's Kentish Town. (environmental-expert.com)
  • Analysis of the barrier heights indicates that the π-bonding between most metals and the alkene is weaker than the σ-bonding. (wikipedia.org)
  • soluble
  • A new water-soluble copper(II) complex bearing 4-bromobenzoate/2,2'-dipyridylamine ligands was successfully synthesized and characterized by using single crystal X-ray diffraction and spectroscopic techniques. (springer.com)
  • This dark green powder is slightly soluble in polar solvents, including water. (wikipedia.org)
  • addition
  • The addition of tri(2-furyl)germane to silyl enolates followed by elimination of germyl and siloxy moieties provides a new route for the conversion of ketones into alkenes. (nii.ac.jp)
  • A new method of anti-Markovnikov addition has been described by Hamilton and Nicewicz, who utilize aromatic molecules and light energy from a low-energy diode to turn the alkene into a cation radical. (wikipedia.org)
  • Formation
  • High levels of water vapor in a natural gas stream can lead to a number of problems which include the formation of hydrates and the contribution to freezing and corrosion of plant and equipment. (environmental-expert.com)
  • complex
  • More complex alkenes may be named with the E-Z notation for molecules with three or four different substituents (side groups). (wikipedia.org)
  • COD-platinum dichloride, (cyclooctadiene)PtCl2, derived from platinum(II) chloride and 1,5-cyclooctadiene, is a common platinum(II) alkene complex. (wikipedia.org)
  • benzene
  • 5. Atom transfer radical cyclization of allyl iodoacetate is much more efficient in water than in benzene. (nii.ac.jp)
  • double
  • For bridged alkenes, Bredt's rule states that a double bond cannot occur at the bridgehead of a bridged ring system unless the rings are large enough. (wikipedia.org)
  • product
  • The position of the alkene in the product is controlled by the site of deprotonation by the organolithium base. (wikipedia.org)
