This route is known for its high yield and ease of execution.
Another synthetic route involves the reaction of 2-bromothiophene-3-carboxylic acid with benzaldehyde in the presence of a boronic acid catalyst such as pinacolboronate.
The reaction occurs in a nonpolar solvent such as benzene or toluene.
This route is known for its high selectivity and the absence of unwanted side reactions.
A third synthetic route involves the reaction of 2-bromothiophene-3-carboxylic acid with benzaldehyde in the presence of a metal catalyst such as copper or zinc.
The reaction occurs in a polar solvent such as water or a mixture of water and an organic solvent.
This route is known for its high efficiency and the ease of operation.
A fourth synthetic route involves the reaction of 2-bromothiophene-3-carboxylic acid with benzaldehyde in the presence of a photocatalyst such as titanium dioxide.
The reaction occurs in the presence of ultraviolet light.
This route is known for its high selectivity and the absence of unwanted side reactions.
A fifth synthetic route involves the reaction of 2-bromothiophene-3-carboxylic acid with benzaldehyde in the presence of a metal catalyst such as palladium or platinum.
The reaction occurs in a polar solvent such as water or a mixture of water and an organic solvent.
This route is known for its high yield and the ease of operation.
A sixth synthetic route involves the reaction of 2-bromothiophene-3-carboxylic acid with benzaldehyde in the presence of a boronic acid catalyst such as boric acid.
The reaction occurs in a nonpolar solvent such as benzene or toluene.
This route is known for its high selectivity and the absence of unwanted side reactions.
A seventh synthetic route involves the reaction of 2-bromothiophene-3-carboxylic acid with benzaldehyde in the presence of a metal catalyst such as iron or cobalt.
The reaction occurs in a polar solvent such as water or a mixture of water and an organic solvent.
This route is known for its high efficiency and the ease of operation.
A eighth synthetic route involves the reaction of 2-bromothiophene-3-carboxylic acid with benzaldehyde in the presence of a photocatalyst such as nickel dioxide.
The reaction occurs in the presence of visible light.
This route is known for its high selectivity and the absence of unwanted side reactions.
In conclusion, there are several synthetic routes for the production of
