The commercial method involves oxidation of phosphorus trichloride with oxygen: [11] 2 PCl 3 + O 2 → 2 POCl 3. An alternative method involves the oxidation of phosphorus trichloride with potassium chlorate: [12] 3 PCl 3 + KClO 3 → 3 POCl 3 + KCl

For example, Cu compounds with Cu oxidation state +2 are called cupric and those with state +1 are cuprous. [4]: 172 The oxidation numbers of elements allow predictions of chemical formula and reactions, especially oxidation-reduction reactions. The oxidation numbers of the most stable chemical compounds follow trends in the periodic table.
r 2 nh + pcl 3 + ch 2 o → (ho) 2 p(o)ch 2 nr 2 + 3 hcl The herbicide glyphosate is also produced this way. The reaction of PCl 3 with Grignard reagents and organolithium reagents is a useful method for the preparation of organic phosphines with the formula R 3 P (sometimes called phosphanes) such as triphenylphosphine , Ph 3 P.

PoCl 2 can be obtained either by halogenation of polonium metal or by dehalogenation of polonium tetrachloride, PoCl 4. [1] Methods for dehalogenating PoCl 4 include thermal decomposition at 300 °C, reduction of cold, slightly moist PoCl 4 by sulfur dioxide; and heating PoCl 4 in a stream of carbon monoxide or hydrogen sulfide at 150 °C.

A new review reports that nine people taking semaglutide and tirzepatide — the active ingredient in GLP-1 medications — experienced vision issues, including three potentially blinding eye ...
The Vilsmeier reagent is an organic compound with the formula [(CH 3) 2 NCHCl]Cl. It is a salt consisting of the N,N-dimethyliminium cation ([(CH 3) 2 N=CHCl] +) and chloride anion. Depending on the particular reaction, the anion can vary. In typical POCl 3-based reactions, the anion is PO 2 Cl 2 −.
