Metal-halogen exchange between hydrazine polyanions and α,α′-dibromo-o-xylene
Lebedev, Oleg,Maeeorg, Uno
, p. 188 - 193 (2014/02/14)
Aromatic-bridged bis(hydrazines) were found to be the main products in the reaction of hydrazine polyanions with α,α′-dibromo-o-xylene. It was confirmed that the reaction is driven by a metal-halogen exchange process. A three-step reaction mechanism is suggested.
