  2. Organozinc chemistry - Wikipedia

    en.wikipedia.org/wiki/Organozinc_chemistry

    The reaction produces a primary, secondary, or tertiary alcohol via a 1,2-addition. The Barbier reaction is advantageous because it is a one-pot process: the organozinc reagent is generated in the presence of the carbonyl substrate. Organozinc reagents are also less water sensitive, thus this reaction can be conducted in water.

  3. Reformatsky reaction - Wikipedia

    en.wikipedia.org/wiki/Reformatsky_reaction

    The Reformatsky reaction (sometimes transliterated as Reformatskii reaction) is an organic reaction which condenses aldehydes or ketones with α-halo esters using metallic zinc to form β-hydroxy-esters: [1] [2] The Reformatsky reaction. The organozinc reagent, also called a 'Reformatsky enolate', is prepared by treating an alpha-halo ester ...

  4. Negishi coupling - Wikipedia

    en.wikipedia.org/wiki/Negishi_coupling

    X = Cl usually leads to slow reactions. The organic residue R = alkenyl, aryl, allyl, alkynyl or propargyl. The halide X' in the organozinc compound can be chloride, bromine or iodine and the organic residue R' is alkenyl, aryl, allyl, alkyl, benzyl, homoallyl, and homopropargyl. The metal M in the catalyst is nickel or palladium

  5. Simmons–Smith reaction - Wikipedia

    en.wikipedia.org/wiki/Simmons–Smith_reaction

    The Simmons–Smith reaction is an organic cheletropic reaction involving an organozinc carbenoid that reacts with an alkene (or alkyne) to form a cyclopropane. [1] [2] [3] It is named after Howard Ensign Simmons, Jr. and Ronald D. Smith.

    The Blaise ketone synthesis (named after Edmond Blaise) is the chemical reaction of acid chlorides with organozinc compounds to give ketones.. The Blaise ketone synthesis. The reaction was claimed to bring excellent yields by Blaise, however, investigators failed to obtain better than moderate yields (50%).

  7. Fukuyama coupling - Wikipedia

    en.wikipedia.org/wiki/Fukuyama_coupling

    The Fukuyama coupling is a coupling reaction taking place between a thioester and an organozinc halide in the presence of a palladium catalyst. The reaction product is a ketone. This reaction was discovered by Tohru Fukuyama et al. in 1998. [1]

  9. Diethylzinc - Wikipedia

    en.wikipedia.org/wiki/Diethylzinc

    Diethylzinc (C 2 H 5) 2 Zn, or DEZ, is a highly pyrophoric and reactive organozinc compound consisting of a zinc center bound to two ethyl groups. This colourless liquid is an important reagent in organic chemistry. It is available commercially as a solution in hexanes, heptane, or toluene, or as a pure liquid.
