1-Butylpyrrolidine Structural

What is 1-Butylpyrrolidine?

The Uses of 1-Butylpyrrolidine

1-Butylpyrrolidine can be used in the composition for alcohol recovery solution.

The Uses of 1-Butylpyrrolidine

1-Butylpyrrolidine has been used in:
microwave-assisted synthesis of ionic liquid precursor, 1-butyl-1-methylpyrrolidinium methylcarbonate.
[N,N-methylbutylpyrrolidinium] thiosalicylate, ionic liquid.
The reaction of 1-butylpyrrolidine with dimethyl carbonate to yield the ionic liquid precursor, 1-butyl-1-methylpyrrolidinium methylcarbonate, has been investigated under microwave heating conditions and the reaction parameters optimised to achieve 100% yield of the pyrrolidinium salt with no by-products in under 1h.

Preparation

The synthesis of 1-butylpyrrolidine and its derivatives (1-butylpyrrolidine with a little of 1-butenylpyrrolidines) was developed via a one-pot method from ammonia and 1,4-butandiol. Here, the product of 1-butylpyrrolidine was emphatically investigated, and the yield was 76% under the optimized conditions. Such a route was realized through successive N-alkylation using aqueous ammonia as the nitrogen source over the CuNiPd/ZSM-5 catalyst, which was prepared by a simple incipient wetness method. In this route, 1,4-butandiol not only participated in the formation of the N-heterocycle, but also acted as an alkylating reagent. This work offers a straightforward, economical route for 1-butylpyrrolidine and its derivatives.
