Structure-dependent transformations of the tetrachlorocyclopentadienone dimer and the product of its substitutive rearrangement in reactions with NaBH4, CrCl2, LiAlH4, and Zn

Abstract

Dechlorination of the tetrachlorocyclopentadienone dimer and perchloro 7 oxotri cyclo[6.1.0.0 4,8 ]nona 2,5 diene 9 carboxylic acid N,N diethylamide with hydride ion donors (NaBH 4 , LiAlH 4 , etc.) and electron donors (CrCl 2 or Zn) were studied. The possible pathways of unusual transformations of both sterically hindered molecules are considered.
