Photoinduced Electron Transfer (PET) as Key to Accelerate the Cycloreversion Reaction of Arylquadricyclanes

Chemistry – A European Journal, EarlyView.
It is demonstrated that the photoinduced cycloreversion of a methoxynaphthylquadricyclane in the presence of suitable photocatalysts gives quantitatively the corresponding norbornadiene. As this photochromic norbornadiene‐quadricyclane cycle has favorable properties for light energy conversion, this method provides a useful tool for the targeted ...

Synthesis of a Functionalized Bicyclo[3.2.1]Octane: A Common Subunit to Kauranes, Grayananes, and Gibberellanes

Chemistry – A European Journal, EarlyView.
A detailed account on the synthesis of a bicyclo[3.2.1]octane scaffold, common to the kaurane, grayanane, and gibberellane diterpenoid families, is reported. Our original strategy relying on a 1,4‐sila‐Prins cyclization proved unsuccessful. Learning from that, we designed an alternative strategy relying on ring‐closing metathesis (RCM), which ...

Synthesis of Cyclobutane‐Containing Tricyclic β‐Lactams Based on a Saturated Scaffold Enabled by Iron‐catalysed [2 + 2]‐Cycloaddition

Chemistry – A European Journal, EarlyView.
First syntheses of pyrrolidine‐, piperidine‐, and azepane tricyclic β‐lactams based on a saturated scaffold are achieved through an Fe‐pyrimidinediimine‐catalysed [2 + 2] cycloaddition of allylamines analogues followed by photo‐induced intramolecular C─H insertion.

London Dispersion versus Intramolecular Hydrogen Bond in Bis‐Pyridines: How Accurate Is DFT for Competing Noncovalent Interactions in the Condensed Phase?

Chemistry – A European Journal, EarlyView.
A test system of 14 singly protonated bis‑pyridine salts, with varying H‑bonded and London dispersion interactions, was designed to systematically study non‑covalent interactions across the gas, solution, and solid phases. A good correlation between the 1H chemical shift and the N‐H–N angle from the crystal structures was established.

Estimating strongly wetting to non‐wetting contact angles for pure and mixed liquids on solids by considering film pressure

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract In solid–liquid–vapour systems, the effect of film pressure (πe$$ {\pi}_e $$) by vapour adsorbate molecules becomes significant when the solid surface energy is similar to or larger than that of the liquid. We extend Young equation applicability to estimate contact angles of pure and mixed liquids on smooth solids by including πe$$ {\pi}_e $$,
