  2. Diazomethane - Wikipedia

    en.wikipedia.org/wiki/Diazomethane

    Diazomethane is an organic chemical compound with the formula CH 2 N 2, discovered by German chemist Hans von Pechmann in 1894. It is the simplest diazo compound.In the pure form at room temperature, it is an extremely sensitive explosive yellow gas; thus, it is almost universally used as a solution in diethyl ether.

    en.wikipedia.org/wiki/Diazo

    Diazo compounds have two main Lewis structures in resonance: R 2 >C-–N + ≡N and R 2 >CH=N + =N-. In organic chemistry, the diazo group is an organic moiety consisting of two linked nitrogen atoms at the terminal position.

  5. Ketene - Wikipedia

    en.wikipedia.org/wiki/Ketene

    General formula for a ketene. In organic chemistry, a ketene is an organic compound of the form RR'C=C=O, where R and R' are two arbitrary monovalent chemical groups (or two separate substitution sites in the same molecule). [1] The name may also refer to the specific compound ethenone H 2 C=C=O, the simplest ketene. [2]

  6. Nierenstein reaction - Wikipedia

    en.wikipedia.org/wiki/Nierenstein_reaction

    If excess diazomethane is present during the reaction, it can act as a base, abstracting a hydrogen from the diazonium-salt intermediate. The result is a neutral diazoketone, which does not react with the chloride. Instead, the byproduct, diazonium-methyl from the other diazomethane molecule, can be attacked by the chloride to produce ...
