Composite Single‐Reference and Explicitly Correlated Multireference Calculations on the Mechanism of Pyrrole Pyrolysis

open access: yesJournal of Physical Organic Chemistry, Volume 39, Issue 4, April 2026.
New calculations have been applied to the pyrolysis of pyrrole under shock‐tube conditions and to the radical‐radical reaction between allyl and •CN at low temperature and pressure, using the same mechanistic scheme for both. ABSTRACT The pyrolysis of pyrrole has previously been studied in shock‐tube experiments and in jet‐stirred reactors. The results
