Cyclopenta‐Fused Polyaromatic Hydrocarbon (CP‐PAH) Radicals: Synthesis, Characterization, and Quantum Chemical Calculations

open access: yesChemistry – A European Journal, Volume 31, Issue 61, November 3, 2025.
Extending the π system of a fully conjugated framework composed of alternating five‐ and six‐membered rings led to further rare examples of bench‐stable carbon‐centered hydrocarbon radicals. Spectroscopic analysis allowed extensive characterization, which was further supported by computational methods.

Aromaticity and Photoreactivity of 4‐ and 3‐Nitrenopyridine 1‐Oxides and Phenylnitrene

open access: yesJournal of Physical Organic Chemistry, Volume 38, Issue 10, October 2025.
NICS(1.7)zz, ACID, and spin density calculations reveal that triplet 4‐nitrenopyridine oxide, 3‐nitrenopyridine oxide, and phenylnitrene display Baird triplet aromaticity. These findings help clarify the relationships between structure and aromaticity in triplet arylnitrenes. ABSTRACT The pursuit of sustainable organic synthesis has renewed interest in

Woodward and Hoffmann on Secondary Orbital Interactions. How to Make a Fine Two‐Course Meal from Leftovers**

open access: yesThe Chemical Record, Volume 25, Issue 9, September 2025.
In February through April 1965, Hoffmann devised several MO tools to explain the regiochemistry of the Diels‐Alder and the preference of the Cope reaction to proceed by the chair rather than boat orientations, when both were possible. The secret lay in secondary orbital interactions that were revealed through qualitative perturbation theory.
