Abstract:
Flash vacuum pyrolysis (FVP) of 1,7‐bis‐(3‐aroylideneamino)‐4,6,10,12‐tetramethyl‐2,8‐dioxo‐1,7‐diazacyclododeca‐3,5,9,11‐tetraene‐3,9‐dicarbonitriles 11a‐c at 650°C and 0.02 Torr yielded 5,7‐dimethyl‐3‐(4‐methylbenzoyl)‐pyrazolo1,5‐a]pyridine‐4‐carbonitrile 14 , 4,6‐dimethyl‐2‐oxo‐1,2‐dihydropyridine‐3‐carbonitrile 16 and 3‐aryl‐3‐oxo‐propionitriles 17a,b . A plausible mechanism is suggested to account for the formation of the products.
