Thiophosphoryl chloride is an inorganic compound with the chemical formula P S Cl 3. [5] It is a colorless pungent smelling liquid that fumes in air. It is synthesized from phosphorus chloride and used to thiophosphorylate organic compounds, such as to produce insecticides.
Phosphoryl chloride (commonly called phosphorus oxychloride) is a colourless liquid with the formula P O Cl 3. It hydrolyses in moist air releasing phosphoric acid and fumes of hydrogen chloride. It is manufactured industrially on a large scale from phosphorus trichloride and oxygen or phosphorus pentoxide. [4] It is mainly used to make ...
In chemistry, phosphorochloridites are a class of organophosphorus compound with the formula (RO) 2 PCl (R = organic substituent). They are pyramidal in shape, akin to regular phosphites (P(OR) 3 ). They are usually colorless and sensitive toward hydrolysis and, to some extent, oxidation to the corresponding phosphorochloridates ((RO) 2 P(O)Cl).
Phosphites, sometimes called phosphite esters, have the general structure P(OR) 3 with oxidation state +3. Such species arise from the alcoholysis of phosphorus trichloride: PCl 3 + 3 ROH → P(OR) 3 + 3 HCl. The reaction is general, thus a vast number of such species are known.
Phosphorus trichloride is a major industrial chemical and widely used starting material for phosphorus chemistry. Phosphorus tribromide is used in organic chemistry to convert alcohols to alkyl bromides and carboxylic acids to acyl bromides ( e.g. in the Hell-Volhard-Zelinsky reaction ).
Lanthanide trichloride, LnCl 3, a class of chemical compound composed of a lanthanide atom and three chloride atoms. Lawrencium trichloride , LrCl 3 , a compound synthesised in 1969 expected to follow other actinide trichlorides.
