Various azohenzenes and azoxy~nzenes were reduced almost quantitatively to the corresponding hydrazohenzenes by sodium dithionite under mild conditions without the formation of aniline derivatives, using dioetyl vioiogen as an electron-transfer catalyst in acetouitrile-water.
The behavior of a viologen polymer (PV 2+ ) as electron-transfer catalyst in the debromination of diphenyl methane bromide (Ph2CHBr) was studied. It was found that Ph2CHBr could be reduced at room temperature by sodium dithionite to afford tetraphenyl ethane in good yields. A mechanism for the debro
