    en.wikipedia.org/wiki/Hunsdiecker_reaction

    The toxic [11] relativistic metals (mercury, thallium, and lead) are preferred: inert counterions, such as the alkali metals, have only rarely led to reported success. [ 12 ] : 464 The Kochi reaction is a variation on the Hunsdiecker reaction developed by Jay Kochi that uses lead(IV) acetate and lithium chloride ( lithium bromide can also be ...

  4. Hydrocarbon - Wikipedia

    en.wikipedia.org/wiki/Hydrocarbon

    In the fossil fuel industries, hydrocarbon refers to naturally occurring petroleum, natural gas and coal, or their hydrocarbon derivatives and purified forms. Combustion of hydrocarbons is the main source of the world's energy. Petroleum is the dominant raw-material source for organic commodity chemicals such as solvents and polymers.

  5. Natural gasoline - Wikipedia

    Natural gasoline is a liquid hydrocarbon mixture condensed from natural gas, similar to common gasoline (petrol) derived from petroleum.. The chemical composition of natural gasoline is mostly five- and six-carbon alkanes (pentanes and hexanes) with smaller amounts of alkanes with longer chains. [1]

  7. Pyrene - Wikipedia

    en.wikipedia.org/wiki/Pyrene

    Pyrene is a polycyclic aromatic hydrocarbon (PAH) consisting of four fused benzene rings, resulting in a flat aromatic system. The chemical formula is C 16 H 10.This yellow-green solid is the smallest peri-fused PAH (one where the rings are fused through more than one face).

  8. Hydrazines - Wikipedia

    en.wikipedia.org/wiki/Hydrazines

    Hydrazines (R 2 N−NR 2) are a class of chemical compounds with two nitrogen atoms linked via a covalent bond and which carry from one up to four alkyl or aryl substituents. . Hydrazines can be considered as derivatives of the inorganic hydrazine (H 2 N−NH 2), in which one or more hydrogen atoms have been replaced by hydrocarbon grou

  9. Wohl–Ziegler bromination - Wikipedia

    en.wikipedia.org/wiki/Wohl–Ziegler_bromination

    The Wohl–Ziegler reaction [1] [2] is a chemical reaction that involves the allylic or benzylic bromination of hydrocarbons using an N-bromosuccinimide and a radical initiator. [3] Best yields are achieved with N-bromosuccinimide in carbon tetrachloride solvent. Several reviews have been published. [4] [5]
