Phosphorus -chloride PCI

At left, the P-NMR references of phosphorus chlorides are depicted in order of decreasing coordination number of phosphorus. However, the coordination number is not expected to be the only ordering principle, as PCI/ would fall outside the range of PCl and the phosphonium salts are seen to resonate significantly upheld from PCI/.

When magnesium is added to water, the reaction is very slow. In contrast, phosphorus(lll) chloride (PCy is a liquid that reacts vigorously with water. One of the products of this reaction is H3PO3, which forms in solution. Write an equation, including state symbols, showing the reaction of phosphorus(iii) chloride with water. [1]... 

Alcohols can also be converted to alkyl halides by phosphorus halides such as PCI PBr3, and PI via an 5 2 mechanism resulting in poor yields with tertiary alcohols. Another reagent for producing alkyl halides from alcohols is thionvl chloride, OCl2, resulting in sulfur dioxide and hydrochloric acid.

The following procedure is useful for preparing " C-bromoacetyl chloride. (l- C)Bromoacetyl chloride was prepared by Hass and Neurath (1971a) by dissolving 693 mg of bromoacetic acid in 20 ml of anhydrous ether and then adding 1.0 gram of phosphorus penta-chloride. After all the PCI 5 had dissolved (about 1 hr) the solution was evaporated on a rotatory evaporator at 30°C.
