Phosphorus trichloride is commonly used to convert primary and secondary alcohols to the corresponding chlorides. [14] As discussed above, the reaction of alcohols with phosphorus trichloride is sensitive to conditions. The mechanism for the ROH →RCl conversion involves the reaction of HCl with phosphite esters: P(OR) 3 + HCl ⇌ HP(OR) + 3 ...

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 ).
Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.
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 ]
μ (Polarity) >0 In chemistry , a trigonal pyramid is a molecular geometry with one atom at the apex and three atoms at the corners of a trigonal base, resembling a tetrahedron (not to be confused with the tetrahedral geometry ).
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.
Alkyl chlorides are most easily prepared by treating alcohols with thionyl chloride (SOCl 2) or phosphorus pentachloride (PCl 5), but also commonly with sulfuryl chloride (SO 2 Cl 2) and phosphorus trichloride (PCl 3): ROH + SOCl 2 → RCl + SO 2 + HCl 3 ROH + PCl 3 → 3 RCl + H 3 PO 3 ROH + PCl 5 → RCl + POCl 3 + HCl
