• named for its discoverer
  • The salt is of historical importance in the area of organometallic chemistry as one of the first examples of a transition metal alkene complex and is named for its discoverer, William Christopher Zeise. (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)
  • 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)
  • 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)
  • molecules
  • 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)
  • More complex alkenes may be named with the E-Z notation for molecules with three or four different substituents (side groups). (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)
  • 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)
  • 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)
  • double bond
  • All you have to remember, is that alkenes contain a double bond. (hubpages.com)
  • 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)
