✦ Synopsis

Polaroghic reduction of some c~uplexl product of acztyl acetone with aryl diazonium chloride takes place in a single Qelectron transfer, giving a diffusion controllcd irreversible waves in B.R. buffers of pH range 2-11.8. The re&ction in these compounds takes place at the -NH-N = C bond. Effect of various cations, anions, surfactant and solvent percentage on the reduction has been discussed.
