A convenient and scalable new synthesis of phenylacetic acids, through the iodide catalyzed reduction of mandelic acids, is based on the in situ generation of Hydroiodic acid From catalytic sodium iodide.

The Phosphorus was discovered by the Brand in 1670. Properties of phosphorus. Phosphorus is part of the nitrogen family along with nitrogen, arsenic, antimony, and bismuth. In 1680, Boyle introduced the use of phosphorus to ignite wooden splints with tips of sulfur, and these later were developed into matches [2]. White Phosphorus. For this it is used Phosphoric acid as a stoichiometric reducer (Jacqueline E. Milne, 2011). P Phosphorus Element information, facts. The following uses for phosphorus are gathered from a number of sources as well as from anecdotal comments. Reaction with oxygen: Yellow phosphorus readily catches fire in air giving dense white fumes of phosphorus pentoxide. Red phosphorus also reacts with oxygen on heating to give phosphorus trioxide or phosphorus pentoxide.

Phosphorus - Phosphorus - Properties and reactions: The electron configuration of the phosphorus atom can be represented by 1s22s22p63s23p3. This is proved by Lavoisier in 1777.Phosphorus exhibits allotropy.It has many variations. In 1772, Scheele built it from the bone-ash.Phosphorus is an element. The periodic table is a chart that that shows how chemical elements are related to each other.

I would be delighted to receive corrections as well as additional referenced uses. The outer shell arrangement therefore resembles that of nitrogen, with three half-filled orbitals each capable of forming a single covalent bond and an additional lone-pair of electrons. Phosphorus was initially used on a wide scale to make poisons, explosives and nerve agents and due to its toxic and lethal properties, it was commonly named as the “devil’s element”. Phosphorus is found in Group 15 (VA) of the periodic table. Most of the remainder is converted to halides or oxides for subsequent use in synthesizing organic phosphorus compounds. Phosphorus is highly reactive and has the following important chemical properties. Phosphorus is a vital plant nutrient and its main use - via phospate compounds - is in the production of fertilizers. White phosphorus is the main among them. Some is used as an alloying agent, some is used to kill rodents, and the rest is employed in chemical synthesis. Phosphorus and phosphites are used as reducing agents in chemical analysis.

A large amount is converted to sulfides used in matches and in the manufacture of insecticides and oil additives. Generally, the White phosphorus is called Phosphorus.. Phosphorus is a catalytic element.
