  2. Buchner ring expansion - Wikipedia

    en.wikipedia.org/wiki/Buchner_ring_expansion

    The Buchner ring expansion is a two-step organic C-C bond forming reaction used to access 7-membered rings. The first step involves formation of a carbene from ethyl diazoacetate , which cyclopropanates an aromatic ring.

  3. Cyclopropanation - Wikipedia

    en.wikipedia.org/wiki/Cyclopropanation

    Cyclopropanation is also stereospecific as the addition of carbene and carbenoids to alkenes is a form of a cheletropic reaction, with the addition taking place in a syn manner. For example, dibromocarbene and cis -2-butene yield cis -2,3-dimethyl-1,1-dibromocyclopropane, whereas the trans isomer exclusively yields the trans cyclopropane.

  4. Büchner–Curtius–Schlotterbeck reaction - Wikipedia

    en.wikipedia.org/wiki/Büchner–Curtius...

    The Buchner–Curtius–Schlotterbeck reaction is the reaction of aldehydes or ketones with aliphatic diazoalkanes to form homologated ketones. [1] It was first described by Eduard Buchner and Theodor Curtius in 1885 [ 2 ] and later by Fritz Schlotterbeck in 1907. [ 3 ]

  5. Carbene - Wikipedia

    en.wikipedia.org/wiki/Carbene

    Carbene cyclopropanation Carbenes add to double bonds to form cyclopropanes , [ 14 ] and, in the presence of a copper catalyst , to alkynes to give cyclopropenes . Addition reactions are commonly very fast and exothermic , and carbene generation limits reaction rate.

  9. Simmons–Smith reaction - Wikipedia

    en.wikipedia.org/wiki/Simmons–Smith_reaction

    The Charette modification replaces the CH 2 I 2 normally found in the Simmons–Smith reaction with aryldiazo compounds, such as phenyldiazomethane, in Pathway A. [30] Upon treatment with stoichiometric amounts of zinc halide, an organozinc compound similar to the carbenoid discussed above is produced. This can react with almost all alkenes and ...
