  2. Isomerization - Wikipedia

    en.wikipedia.org/wiki/Isomerization

    In certain kinds of alkene polymerization reactions, chain walking is an isomerization process that introduces branches into growing polymers. [citation needed] The trans isomer of resveratrol can be converted to the cis isomer in a photochemical reaction. [6] Thermal rearrangement of azulene to naphthalene has been observed. [7]

  3. Alicyclic compound - Wikipedia

    en.wikipedia.org/wiki/Alicyclic_compound

    Bicyclic alkenes include norbornene and norbornadiene. Two more examples are shown below, methylenecyclohexane on the left and 1-methylcyclohexene on the right: Left: exocyclic double bond Right: regular double bond. An exocyclic group is always shown outside the ring structure, take for instance the exocyclic double bond of the former molecule.

  4. 1-Bromopropane - Wikipedia

    en.wikipedia.org/wiki/1-Bromopropane

    1-Bromopropane (n-propylbromide or nPB) is a bromoalkane with the chemical formula CH 3 CH 2 CH 2 Br. It is a colorless liquid that is used as a solvent. It has a characteristic hydrocarbon odor.

  5. Olefin metathesis - Wikipedia

    en.wikipedia.org/wiki/Olefin_metathesis

    In organic chemistry, olefin metathesis is an organic reaction that entails the redistribution of fragments of alkenes (olefins) by the scission and regeneration of carbon-carbon double bonds. [ 1 ] [ 2 ] Because of the relative simplicity of olefin metathesis, it often creates fewer undesired by-products and hazardous wastes than alternative ...

  6. Transition metal alkene complex - Wikipedia

    en.wikipedia.org/wiki/Transition_metal_alkene...

    The barrier for the rotation of the alkene about the M-centroid vector is a measure of the strength of the M-alkene pi-bond. Low symmetry complexes are suitable for analysis of these rotational barriers associated with the metal-ethene bond.In Cp Rh(C 2 H 4 )(C 2 F 4 ), the ethene ligand is observed to rotate with a barrier near 12 kcal/mol but ...

    A [3+2]-cycloaddition with the alkene (3) gives the cyclic intermediate 4. [ 9 ] [ 10 ] Basic hydrolysis liberates the diol ( 5 ) and the reduced osmate ( 6 ). Methanesulfonamide (CH 3 SO 2 NH 2 ) has been identified as a catalyst to accelerate this step of the catalytic cycle and if frequently used as an additive to allow non-terminal alkene ...
