The synthetic routes of 4-nitroindan have evolved over time, and several methods have been developed to synthesize this compound.
In this article, we will discuss the synthetic routes of 4-nitroindan and their importance in the chemical industry.

Early Synthetic Routes

The early synthetic routes for 4-nitroindan involved the use of nitrating agents such as nitric acid, and were often dangerous and inefficient.
These methods also produced a mixture of products, and it was difficult to obtain pure 4-nitroindan.

Later Synthetic Routes

Later, more efficient and safer synthetic routes for 4-nitroindan were developed.
One of the most common methods involved the reduction of 4-nitrobenzaldehyde using hydrogen in the presence of a catalyst such as palladium on charcoal.
This method produced pure 4-nitroindan, and was much safer and more efficient than the earlier methods.

Modern Synthetic Routes

In modern times, several other methods have been developed for the synthesis of 4-nitroindan.
One of the most widely used methods is the nitration of indanone, which involves the conversion of indanone to 4-nitroindan using nitric acid and a polymeric nitrate catalyst.
This method is highly efficient and produces high yields of pure 4-nitroindan.

Another modern method for the synthesis of 4-nitroindan involves the use of microwave irradiation.
In this method, indanone is nitrated using nitric acid and a microwave source, and pure 4-nitroindan is produced in good yields.
