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

The Chemical Record, EarlyView.
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.

Supporting the Emergence of Science Capital in Minoritized Youth Through Guided Experiences as Facilitators of Science Outreach

Journal of Research in Science Teaching, EarlyView.
ABSTRACT This study explored how minoritized youth‐guided experiences as facilitators of science outreach activities in their community can become a powerful pathway to developing their science capital. The educational setting was the Gap‐Year Program run by Alrowad for Science and Technology.

NaSC2H: A First Crystalline Compound with a −SC2H Anion, an Isolobal Variant of Ubiquitous −SCN

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Crystalline NaSC2H was obtained by reacting NaC2H with elemental sulfur in liquid ammonia. It contains −SC2H anions, which was confirmed by infrared and Raman spectroscopy as well as by structural elucidation based on synchrotron powder diffraction data. −SC2H is a new isolobal variant of the ubiquitous −SCN anion (thiocyanate).
