Angewandte Chemie, Volume 137, Issue 23, June 2, 2025.Stable imino‐substituted Au(III) carbenes are easily and efficiently prepared by trapping the transient (N^C^C)Au←:CH(dmp)+ carbene with nitriles. The corresponding free species are readily generated and display dual carbene / nitrile‐ylide reactivities. The diazo decomposition, nitrile insertion, and carbene transfer can be combined in three‐component

Journal 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
