- Title
Dehydrogenation of 2-Phenyl-1-pyrroline with Palladium-Supported Catalysts: An Effective Route to the Synthesis of 2-Phenylpyrrole.

Figueira, Cláudia; Gomes, Pedro
- Abstract
The catalytic dehydrogenation of 5-phenyl-3,4-dihydro-2 H-pyrrole (2-phenyl-1-pyrroline) to 2-phenyl-1 H-pyrrole in the presence of palladium-supported on activated carbon (Pd/C) or on alumina (Pd/AlO) is reported. Highly pure 2-phenylpyrrole is obtained in good yields and selectivities, in a ca. 20 gram-scale, after a simple work-up. The Pd/AlO catalyst exhibited substantially higher activities than the Pd/C ones. Graphical Abstract: [Figure not available: see fulltext.]
