Tautomerism of O-acyl and O-alkylidenpropanedinitrile groups in trihalotropolones and dithiotropolones
Hartke,Sauerbier
, p. 477 - 482 (2007/10/02)
The thallium(I)-trihalotropolonates 4 react with benzoyl chloride (5) or (1 chlorobenzylidene)propanedinitrile (7) to form the O-benzoyl-trihalotropolones 6 or the O-(benzylidenepropanedinitrile)trihalotropolones 8. Both of them show a rapid migration of
