Synthesis and thiolation of 1,3-difluoro-2,4,6-trihaloanilines and benzenes
Manka, Jason T.,Kaszynski, Piotr
, p. 39 - 43 (2007/10/03)
Three pentahaloanilines were prepared by stepwise halogenation of 3,5-difluoroaniline and were deaminated to form pentahalobenzenes. Alternatively, two pentahalobenzenes were obtained by lithiation followed by iodination of 1,3-difluoro-4,6-dihalobenzenes
