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

Erratum

Erratum to: Catal Lett (2015) 145:762–768 DOI 10.1007/s10562-014-1469-0

The original version of this article unfortunately contained an error in Table 1. The unit mentioned in the header of last column in Table 1 (TOF) should be changed to min−1 instead of s−1. The correct table is given below.
