Abstract
A new series of organotellurium compounds derived from 4,-4-dihydroxy azobenzen have been prepared by the reaction of 3-HgC1-4-OH-C6H3N=NC6H4-OH (A) with TeBr4 and P-CH3OC6H4TeBr3 to give (3-(P-CH3OC6H4TeBr2)-4-OHC6H3-N=N-C6H4-OH) (B̅) and (3-TeBr3-4-OHC6H3N=NCH4-OH) (B) respectively, reduction of B by sodium sulphide gave the corresponding organotellurenyl compound (C), (3-TeBr-4-OH-CH3N=N-C6H4-OH). Compound (D) (OH-C6H4-N=N-CH3-4-OH-3Te)2 has been prepared by reduction of compound B or C by hydrazine hydrate. Reduction of B̅ gave the corresponding telluride 3-(P-CH3OCH4Te)-4-OH-CH3N=N-C6H4-4-OH (E). All compounds have been characterized, by IR and 1H NMR spectral data and meting point was determined. The molar conductivities of the halogenated compounds (B, B̅,C) in DMSO and DMF show some weak electrolytic behavior.
