Further, Small-Molecule Pyrolysis Products Derived from Chitin*

In an ongoing study of the products formed on pyrolysis of chitin (4) under a range of conditions, we now detail the isolation and characterisation of the crystalline and hitherto undetected pyridine N-oxide 18 and enamide 19. Pathways for the formation of these products have been proposed and subjected to both experimental and computational assessment.
