Tricks for Conversions in Organic Chemistry

✅Haloalkanes can give you every possible functional group. They can also help you in increasing the chain size. So you might want to convert your starting material to haloalkanes and then go to the desired product

✅Remember the series of oxidation/reduction: Hydrocarbons (with various substituents) can be oxidised to alcohols, then appropriate carbonyl compounds and lastly carboxylic acids (or their derivatives)

✅Strong oxidizing agents are KMnO4 and K2Cr2O7

✅Mild oxidising agents depending on the situation are CrO4, Ammoniacal AgNO3, Benedicts Solution, Fehling’s solution, Cu or CuO at 573K, Bromine water etc.

✅Any carboxylic acid derivative can be converted back to the carboxylic acid by hydrolysis.

✅There are possibilities of hydride and methyl to get the most stable intermediate (carbocation/free radical)

✅A most common reaction, if your starting material is an alkane, is free-radical halogenation.

✅Saytzeff/Markovnikov's rules must be kept in mind while dealing with alkenes (they are based on the electron displacement effects only)

✅Decarboxylation and ozonolysis could go-to methods for decreasing the number of carbon atoms

✅Grignard reagent gives you the much-needed Alkyl nucleophile, which can be used at appropriate places.

Oxymercuration-Demercuration of Alkenes : alkene alkoxymercuration-demercuration to give an alcohol.

Reaction type: Electrophilic Addition

Summary
Overall transformation C=C to H-C-C-OH
This is an alternative method for hydrating alkenes to give alcohols.
Typical reagents are mercury acetate, Hg(OAc)2 in aqueous THF Unfortunately, mercury compounds are generally quite toxic.
Regioselectivity predicted byMarkovnikov's rule (most highly substituted alcohol).The reaction is not stereoselective. Reaction proceeds via the formation of a cyclic mercurinium ion (compare with bromination of alkenes).
The mercurinium ion is opened by the attack of water to complete the oxymercuration.
When the water attacks, it does so at the more highly substituted carbon.
Demercuration is effected by a reduction using sodium borohydride, NaBH4
If the reaction is carried out in the presence of an alcohol rather than water, then ethers are obtained via an alkoxymercuration :
alkoxymercuration-demercuration to give an ether
The only difference here is a change in the nucleophile from H2O to ROH

MECHANISM FOR REACTION OF ALKENES WITH Hg(OAc)2 / H2O
Step 1:
The C=C π electrons act as the nucleophile with the electrophilic Hg and loss of an acetate ion as a leaving group, forming the mercurinium ion.
oxymercuration / demercuration of C=C
Step 2:
Water functions as a nucleophile and attacks one of the carbons substituted with mercury resulting in cleavage of the C-Hg bond.
Step 3:
The acetate ion functions as a base deprotonating the oxonium ion to give the alcohol. This completes the oxymercuration part of the reaction.
Step 4:(mechanism not shown)
The hydride reduces the Hg off, creating a C-H bond while breaking the C-Hg bond. This is the demercuration part of the process.
