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. Two new, small molecule pyrolysis products, 18 and 19 , derived from acid-treated chitin (4) are reported. [ABSTRACT FROM AUTHOR]
