Chitin represents an abundant source of nitrogenous polysaccharides, making it a suitable feedstock for organonitrogen platform chemicals. In particular, furanic compounds, such as 3-acetamido-5-acetylfuran (3A5AF), can be readily obtained. Furans can be further functionalized using a Diels–Alder (DA) …

We have investigated the photoionization and photodissociation of free coronene cations C24H12+ upon soft X-ray photoabsorption in the carbon K-edge region by means of a time-of-flight mass spectrometry approach. Core excitation into an unoccupied molecular orbital (below threshold) and core ionization …
