Flash Vacuum Pyrolysis (FVP) of 3‐ t ‐Butylindeno[1,2‐ c ]isoxazol‐4‐one ( 1 ) and 3‐ t ‐Butylspiro[2 H ‐azirine‐2,2′‐(2 H )indene]‐1′,3′‐dione ( 2 ) were carried out. Reaction of 1 from 300–400° afford 2 and 2‐carbonyl‐1,3‐indandione 2‐azine ( 3 ) as the major products, whereas 2‐ t ‐Butylindeno[1,3‐ c ]oxazol‐4‐one ( 4 ) was the main products in FVP of 2 together with minor amounts of 3.
