4‐Substituted thiosemicarbazides 4a‐c reacted with (2,4,7‐trinitro‐9__H__‐fluoren‐9‐ylidene)‐propanedinitrile (2) in pyridine with admission of air to form spiro[fluorene‐9,3′‐(1,2,4‐triazole)]derivatives 5a‐c and (4‐substituted thiosemicarbazono)propanedinitriles 6a‐c in modest yields. 2,4,7‐Trinitro‐9‐fluorenone (8) as well as one reduction product thereof and of 2, namely compounds 9 and 10, respectively are also found. A rationale for the conversions observed is presented.
