Two are the Nozaki-Hiyama-Kishi reaction (1977) (transmetallation with organonickel intermediate) and the Takai olefination (1986)(oxidation of Cr(II) to Cr(III) while replacing halogens). Because plastics are made of carbon, polymer chemistry is part of organic chemistry. The distinction between the two disciplines is far from absolute, as there is much overlap in the subdiscipline of organometallic chemistry. The Journal of Physical Organic Chemistry is a monthly peer-reviewed scientific journal, published since 1988 by John Wiley & Sons. A few organoarsenic compounds, also called "organoarsenicals," are produced industrially with uses as insecticides, herbicides, and fungicides. [2] The area remains less developed relative to the chemistry of other main-group elements , because Be compounds are toxic and few applications have been found. Chem. Organic chemistry is a chemistry subdiscipline involvin the scientific study o the structur, properties, an reactions of organic compoonds an organic materials, Starting in the 1970s, analytical chemistry became progressively more inclusive of biological questions (bioanalytical chemistry), whereas it had previously been largely focused on inorganic or small organic molecules.
