experimental of reaction between pyridine and PCl5
Benzylidenecyclopentanone Draw its structure by attaching C6H5-CH= to carbon 2 of cyclopentanone.
The reaction will proceed to the left. PCl5 will be formed. PCl3 will be consumed.
When pyridine reacts with sodamide, the products obtained are sodamide anion (NaNH2) and a protonated pyridine molecule. The NaNH2 acts as a strong base and abstracts a proton from the pyridine molecule to form sodamide anion and a protonated pyridine.
Pyridine is used in the synthesis of aspirin as a catalyst to help facilitate the esterification reaction between salicylic acid and acetic anhydride. Its basic properties help neutralize the acidic byproducts formed during the reaction, which improves the yield of aspirin. Additionally, pyridine can also help dissolve the reactants and promote the formation of the desired product.
3-Hydroxy pyridine can be prepared by treating pyridine with an oxidizing agent such as hydrogen peroxide in the presence of a catalyst such as platinum or palladium. This reaction converts the nitrogen atom in pyridine to a hydroxyl group, yielding 3-hydroxy pyridine as the product. Purification steps may be required to isolate the final compound.
Benzylidenecyclopentanone Draw its structure by attaching C6H5-CH= to carbon 2 of cyclopentanone.
The decomposition reaction for PCl5 is represented as follows: PCl5 (s) → PCl3 (g) + Cl2 (g). This reaction involves the breaking down of solid phosphorus pentachloride (PCl5) into gaseous phosphorus trichloride (PCl3) and chlorine gas (Cl2). The reaction is endothermic, requiring energy input to break the bonds within the PCl5 molecule.
The reaction between osmium tetroxide (OsO4) and pyridine-NaHSO3 in the presence of water involves the formation of a complex between OsO4 and pyridine-NaHSO3, which is stabilized by water molecules. This complexation reaction helps in the reduction of osmium tetroxide to osmium dioxide, resulting in the formation of a stable product.
The reaction will proceed to the left. PCl5 will be formed. PCl3 will be consumed.
Pyridine acts as a catalyst in chemical reactions by facilitating the formation of new bonds between molecules. It can also stabilize reactive intermediates and help control the reaction conditions.
In the pyridine SN2 reaction, a nucleophile attacks the carbon atom of a pyridine ring, displacing a leaving group. This process occurs in a single step, with the nucleophile replacing the leaving group on the pyridine ring.
When pyridine reacts with sodamide, the products obtained are sodamide anion (NaNH2) and a protonated pyridine molecule. The NaNH2 acts as a strong base and abstracts a proton from the pyridine molecule to form sodamide anion and a protonated pyridine.

Pyridine is used in the synthesis of aspirin as a catalyst to help facilitate the esterification reaction between salicylic acid and acetic anhydride. Its basic properties help neutralize the acidic byproducts formed during the reaction, which improves the yield of aspirin. Additionally, pyridine can also help dissolve the reactants and promote the formation of the desired product.
The balanced equation for the reaction is P2S5 + 5 PCl5 → 5 PSCl3.
The nucleophilic substitution reaction occurs at position 2 in pyridine because it is the most sterically accessible site due to the presence of the nitrogen lone pair at that position. The aromaticity of the pyridine ring also plays a role in stabilizing the intermediate formed during the substitution reaction at this position.
The reactivity of TsCl (thionyl chloride) with pyridine in organic synthesis is high. TsCl is commonly used as a reagent to convert alcohols to chlorides in the presence of pyridine, which acts as a base to facilitate the reaction. This reaction is often used in the synthesis of various organic compounds.
