Dichtheid pocl3
WebThe first equation shows the dehydration of a 3º-alcohol. The predominance of the non-Zaitsev product (less substituted double bond) is presumed due to steric hindrance of the methylene group hydrogen atoms, which interferes with the approach of base at that site. The second example shows two elimination procedures applied to the same 2º-alcohol. WebSo POCl3 and pyridine are going to do an elimination reaction on an alcohol and make a double bond. That's all you need to know right now in terms of the general reaction. Now …

WebFeb 27, 2024 · However, if you were to treat pyridine N-oxide with phosphorus oxychloride $\ce{POCl3}$, then you would see chlorination at C-2. If you have a source that says that $\ce{PCl3}$ can deoxygenate and chlorinate, please do inform us. Otherwise as far as I can tell, you need $\ce{POCl3}$ to effect a chlorination. References grand rapids to newarkPhosphoryl chloride (commonly called phosphorus oxychloride) is a colourless liquid with the formula POCl3.
