Why is dry ether necessarily used for #C-C# bond formation reactions?

Answer 1

You might have to clarify here........

Are you asking about a Grignard reaction, which is the premier #C-C# bond-making reaction in all of organic chemistry?
#R-X+Mgstackrel("dry ether")rarrR-MgX#

Additionally, the so-called Grignard reagent produces alcohols and carboxylic acids (upon work-up) when it reacts with dry ice, ketones, and aldehydes.

Because Grignards and lithium reagents are extremely sensitive to water, chemists take great care and precautions to use dry solvents and dry glassware in order to prevent degrading the Grignard reagent. It is thought that the dry ether (diethyl ether or THF) solvates the Grignard reagent and brings the organometallic species up into solution.

#R_1R_2R_3C-MgX +""^2H_2OrarrR_3C^2H +MgXO""^2H#

Thus, an alkyl residue with a deuterium nucleus can be labeled for use in a unique reaction.

Answer 2

As an inert solvent that does not react with the reactants or products involved in the reaction, dry ether is used in C-C bond formation reactions to ensure that the reaction proceeds smoothly and without interference from the solvent, resulting in higher yields and purity of the desired products. Dry ether also aids in the dissolution of the reactants and facilitates their interaction, thereby promoting the formation of C-C bonds efficiently.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
